SN74LVCE161284VR

Specialty Logic Overview

The SN74LVCE161284 is a 19-bit IEEE Std 1284 translation transceiver designed for 3-V to 3.6-V VCC operation, with VCC CABLE supporting 3-V to 5.5-V ranges. It provides asynchronous two-way communication between data buses via eight bidirectional bits and five cable-side drivers. The device features an auto-power-up function that prevents printer errors during power-on by keeping Y outputs high until valid signals are detected. Integrated 1.4-kΩ pullup resistors on open-drain outputs eliminate the need for discrete components.

Specialty Logic Feature Summary

• Auto-Power-Up feature prevents printer errors when the printer is turned on without valid signals at A9–A13 pins
• Integrated 1.4-kΩ pullup resistors on all open-drain outputs eliminate the need for discrete resistors
• Designed for IEEE Std 1284-I (Level-1 Type) and IEEE Std 1284-II (Level-2 Type) electrical specifications
• Flow-through architecture optimizes PCB layout

Specialty Logic Applications

• IEEE Std 1284 parallel peripheral interface systems
• Printer-to-host translation transceivers
• Bi-directional data bus communication interfaces

Specialty Logic Procurement Notes

Verify the specific package variant (DL SSOP or DGG TSSOP) and suffix (DGGR tape-and-reel or DLR tape-and-reel) against your bill of materials. Confirm operating temperature range requirements match the 0°C to 70°C specification. Ensure supply voltage constraints align with the 3-V to 3.6-V VCC and 3-V to 5.5-V VCC CABLE limits before procurement.

Specialty Logic Selection Notes

Select this component for applications requiring IEEE 1284 compliance with integrated pullup resistors. Consider the flow-through architecture for simplified PCB routing. Verify that the 0°C to 70°C operating temperature range meets environmental requirements. Ensure system design accommodates the dual-supply voltage configuration for peripheral and cable sides.

Specialty Logic Part Context
