SN74LVCZ161284AGR

Specialty Logic Overview

The SN74LVCZ161284AGR is a low-voltage translating transceiver designed to implement a full IEEE 1284 compliant interface. It contains eight bidirectional data buffers and eleven control/status buffers, supporting Extended Capabilities Port (ECP) mode. The device facilitates easy connection from the peripheral side to the host cable side. It supports IEEE 1284 Level 1 and Level 2 signaling standards for bidirectional parallel communications between personal computers and printing peripherals.

Specialty Logic Feature Summary

• Translation capability allows outputs on the cable side to interface with 5V signals
• All inputs have hysteresis to provide noise margin
• B and Y output resistance optimized to drive external cable
• Power-up protection prevents errors when the printer is powered on but no valid signal is at the input pins

Specialty Logic Applications

• Extended Capabilities Port (ECP) mode implementation
• Bidirectional parallel communications between personal computers and printing peripherals
• Peripheral to Host cable side interface

Specialty Logic Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or ON Semiconductor, as Texas Instruments does not typically produce this specific part number in public catalogs. Confirm the package type matches the 'AGR' suffix requirements. Ensure the datasheet explicitly lists IEEE 1284 compliance and power-up protection features before procurement.

Specialty Logic Selection Notes

Select this component when a low-voltage translating transceiver is required for IEEE 1284 interfaces. It replaces the function of two 74ACT1284 devices. Consider its flow-through pin configuration for easy interface between Peripheral and Host sides. Verify voltage compatibility if interfacing with 5V systems via its translation capabilities.

Specialty Logic Part Context

This component belongs to the LVXZ series of low-voltage translating transceivers. It is functionally equivalent to the 74LVXZ161284. The device is intended for use in environments requiring robust bidirectional data transfer with noise immunity and power-up safety features.

Specialty Logic Replacement Considerations

The 74LVXZ161284 is a confirmed functional substitute. Verify pinout compatibility and voltage levels before substitution.
