Texas Instruments SN74LVTH162373 3.3-V ABT 16-Bit Transparent D-Type Latches With 3-State Outputs SN74LVTH162373DLR

The SN74LVTH162373 is a 3.3-V ABT 16-bit transparent D-type latch with 3-state outputs, designed for low-voltage operation while supporting TTL interface compatibility with 5-V systems. It features a buffered output-enable input that allows the outputs to be placed in a high-impedance state, facilitating bus line driving without additional components. The device can source or sink up to 12 mA and includes built-in 22-ohm series resistors to minimize overshoot and undershoot. This latch supports mixed-mode signal operation and is suitable for applications requiring unregulated battery operation down to 2.7 V. It incorporates active bus-hold circuitry to maintain valid logic levels on unused inputs, eliminating the need for external pull-up or pull-down resistors. The SN74LVTH162373 is fully specified for hot-insertion applications, with I_off and power-up 3-state support to prevent damaging current backflow during power transitions. The operating temperature range is from -40¬8C to 85¬8C, making it suitable for a variety of environments.
