74FCT162H952ATPACT

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74FCT162H952ATPACT is a 16-bit registered transceiver housed in a 56-lead TSSOP package. It operates within an industrial temperature range of -40°C to +85°C and requires a VCC supply of 5V ± 10%. The device features balanced 24 mA output drivers and includes bus hold functionality on data inputs to retain the last active state, eliminating the need for external pull-up or pull-down resistors. It supports partial-power-down mode via Ioff circuitry to prevent damaging current backflow when powered down.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the purpose of the bus hold feature?

The bus hold feature retains the last active state of the input whenever it goes to high impedance, preventing floating inputs without external resistors.

How does the device support partial-power-down?

The Ioff circuitry disables the outputs to prevent damaging current backflow through the device when it is powered down.
