SN74LV161284ADGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV161284ADGGR is a 19-bit bus interface designed for 4.5-V to 5.5-V VCC operation, featuring asynchronous two-way communication between data buses. It includes eight bidirectional bits controlled by the DIR pin, five drivers for the cable side, and four receivers. The device supports IEEE Std 1284-I (Level-1 Type) and IEEE Std 1284-II (Level-2 Type) specifications. Integrated 1.4-kΩ pullup resistors on all open-drain outputs eliminate discrete components. It operates within a temperature range of -40°C to 85°C in a 48-pin TSSOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix matches the required package type and tape-and-reel quantity. Confirm RoHS compliance status and moisture sensitivity level ratings before procurement. Ensure the specific variant aligns with the intended operating temperature range and voltage requirements for the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems compliant with IEEE Std 1284 standards requiring robust ESD protection and integrated pullup resistors. Consider the dual-supply capability if voltage translation between host logic and cable-side peripherals is necessary. Evaluate the 48-pin TSSOP package constraints against available PCB real estate and thermal dissipation requirements.
