74FCT162H543CTPACT

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74FCT162H543CTPACT is a 16-bit latched transceiver organized as two independent 8-bit D-type latched transceivers. It operates within an industrial temperature range of -40°C to +85°C and requires a supply voltage (VCC) of 5V ± 10%. The device features bus hold on data inputs, eliminating the need for external pull-up or pull-down resistors. It utilizes a 56-lead TSSOP package with a 19.6-mil pitch. Electrical characteristics include a typical propagation delay of 5.1 ns in transparent mode and balanced 24 mA output drivers.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Bus hold functionality retains the last active state on data inputs when they go high impedance, preventing floating inputs without external components.
• Edge-rate control circuitry improves noise characteristics by reducing system switching noise and ground bounce.
• Supports partial-power-down mode operation through Ioff circuitry that disables outputs to prevent damaging current backflow.
• Provides independent control of inputting and outputting in either direction of data flow via separate latch and output enable controls.

Buffers, Drivers, Receivers, Transceivers Applications

• Driving high-capacitance loads and low-impedance backplanes
• Partial-power-down applications requiring power management
• Systems needing elimination of external pull-up or pull-down resistors

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'TPACT' corresponds to the 56-lead TSSOP package with a 2000-unit reel quantity. Confirm the component status is Active for new designs. Ensure compatibility with the specified 5V ± 10% supply voltage and industrial temperature range requirements for your application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when 16-bit registered data transfer with bus hold capability is required. It is suitable for designs needing reduced ground bounce and improved noise performance compared to standard FCT devices. Consider the 56-lead TSSOP package constraints and verify that the 24 mA balanced output drivers meet the load requirements of the target bus architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the CY74FCT162H543T series of 16-bit latched transceivers manufactured by Texas Instruments. It is derived from Cypress Semiconductor technology acquired by TI. The device is distinct from the CY74FCT16543T and CY74FCT162543T variants primarily due to its integrated bus hold feature on the data inputs.
