PRODUCT OVERVIEW

What Is the CLVC16T245MDGGEP?

CLVC16T245MDGGEP (SN74LVC16T245-EP) is a 16-bit noninverting bus transceiver from Texas Instruments that uses two separate configurable power-supply rails. The A port is designed to track VCCA, which accepts any supply voltage from 1.65V to 5.5V. The B port is designed to track VCCB, which also accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between 1.8V, 2.5V, 3.3V, and 5V voltage nodes.[reference:5][reference:6]

The device is designed for asynchronous communication between data buses, with the direction-control (DIR) input and output-enable (OE) input activating either the B-port outputs or the A-port outputs or placing both output ports into the high-impedance mode. The control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by VCCA.[reference:7]

The SN74LVC16T245-EP supports defense, aerospace, and medical applications with controlled baseline, one assembly and test site, one fabrication site, extended product life cycle, and product traceability. It is available in the military temperature range of -55°C to +125°C.[reference:8]

Configurable Voltage Translation Dual-rail design allows each port to operate from 1.65V to 5.5V for universal translation between 1.8V, 2.5V, 3.3V, and 5V nodes.

Enhanced Product (EP) Supports defense, aerospace, and medical applications with controlled baseline and full traceability.

Military Temperature Range Guaranteed operation from -55°C to +125°C for harsh environments.

DEVICE HIGHLIGHTS

Key Features and Benefits of CLVC16T245MDGGEP

Configurable Dual-Rail Voltage Translation

Fully configurable dual-rail design allows each port to operate over the full 1.65V to 5.5V power-supply range, enabling universal translation between 1.8V, 2.5V, 3.3V, and 5V logic levels.[reference:9]

VCC Isolation & Partial-Power-Down Support

VCC isolation feature ensures both ports are in high-impedance state if either VCC input is at GND. Ioff circuitry prevents damaging current backflow during partial-power-down.[reference:10][reference:11]

Military Temperature Range

Guaranteed operation from -55°C to +125°C with controlled baseline, one assembly/test/fabrication site, and full product traceability.[reference:12]

Wide Supply Voltage Range

Each port accepts any supply voltage from 1.65V to 5.5V, compatible with 1.8V, 2.5V, 3.3V, and 5V systems.[reference:13]

16-Bit Bidirectional Translation

Two 8-bit sections with independent direction and output-enable controls provide flexible 16-bit bidirectional bus translation in a single package.[reference:14]

Robust ESD & Latch-Up Protection

ESD protection exceeds 2000-V HBM, 200-V MM, and 1000-V CDM. Latch-up performance exceeds 100mA per JESD 78, Class II.[reference:15]

DESIGN REFERENCE

Circuit Considerations for CLVC16T245MDGGEP

Voltage Translation & Control Logic

The SN74LVC16T245-EP consists of two 8-bit sections with independent direction and output-enable controls:

DIR Inputs (1DIR, 2DIR): Logic HIGH = A data to B bus; Logic LOW = B data to A bus
OE Inputs (1OE, 2OE): Logic LOW enables outputs; Logic HIGH places outputs in high-impedance state
Control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by VCCA[reference:16]
Unused data inputs must be held at VCCA or GND to prevent excess ICC and ICCZ[reference:17]

PCB and Power-Supply Guidance

Bus transceiver performance depends on layout, bypassing, and power sequencing:

Bypass each VCC pin with a 0.1µF ceramic capacitor placed as close to the device as possible
To ensure high-impedance state during power-up/power-down, OE should be tied to VCC through a pullup resistor[reference:18]
VCC isolation ensures both ports are high-impedance if either VCC is at GND[reference:19]
Ioff circuitry disables outputs during partial-power-down, preventing damaging current backflow[reference:20]
Verify the recommended PCB footprint from the official datasheet before production
