PRODUCT OVERVIEW

What Is the SN74LVTH16244ADGGR?

SN74LVTH16244ADGGR is a 16-bit buffer and line driver from Texas Instruments, part of the SN74LVTH16244A family and a member of the Widebus™ family. The device is designed for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

The device is organized as four 4-bit buffers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. The SN74LVTH16244A can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer, providing flexible system integration.

The device features state-of-the-art advanced BiCMOS technology (ABT) design for low static-power dissipation and supports mixed-mode signal operation with 5-V input and output voltages at 3.3-V VCC. Active bus-hold circuitry holds unused or undriven inputs at a valid logic state, eliminating the need for external pullup or pulldown resistors. The SN74LVTH16244ADGGR is fully specified for hot-insertion applications using Ioff and power-up 3-state circuitry, which places the outputs in the high-impedance state during power up and power down. The device is offered in a 48-lead TSSOP (DGG) package and is rated for operation from –40°C to +125°C.

16-Bit Buffer/Driver Four 4-bit buffers with independent output-enable (OE) inputs, configurable as 4-bit, 8-bit, or 16-bit operation.

Mixed-Mode Signal Operation Supports 5-V input and output voltages with 3.3-V VCC for TTL interface to 5-V systems.

Hot-Insertion & Bus-Hold Support Ioff and power-up 3-state circuitry for hot insertion; bus-hold on data inputs eliminates external resistors.

Circuit Considerations for SN74LVTH16244ADGGR

Power Supply & Key Features

The SN74LVTH16244ADGGR requires proper power supply design for optimal performance:

Supply Voltage: Operates with VCC from 2.7 V to 3.6 V, supporting unregulated battery operation down to 2.7 V
Mixed-Mode Operation: Supports 5-V input and output voltages with 3.3-V VCC, enabling TTL interface to 5-V systems
Bus-Hold Circuitry: Active bus-hold holds unused or undriven inputs at a valid logic state; use of pullup or pulldown resistors is not recommended
Hot-Insertion Support: Ioff circuitry disables outputs, preventing damaging current backflow when powered down; power-up 3-state places outputs in high-impedance state during power up and down

PCB and Signal Integrity Guidance

Buffer/Driver performance depends on layout and signal routing:

Output Enable Control: Four independent OE inputs control each 4-bit bank; when OE is low, data passes from A inputs to Y outputs; when OE is high, outputs are in high-impedance state
Power-Up/Power-Down: To ensure high-impedance state above 1.5 V, OE should be tied to VCC through a pullup resistor; minimum resistor value is determined by the current-sinking capability of the driver
3-State Outputs: When OE is high, outputs are in the high-impedance state, allowing multiple outputs to be connected to a common bus
Ground Plane: Use a solid ground plane to minimize noise and ensure low-inductance return paths
Trace Routing: Keep bus traces short and maintain controlled impedance for high-speed operation
PCB Layout: Follow the recommended PCB footprint from the official datasheet prior to production
