74ABT162501DGGRE4

Overview

The SN74ABT162501DGGRE4 is an 18-bit universal bus transceiver with 3-state outputs manufactured by Texas Instruments. It utilizes state-of-the-art EPIC-II BiCMOS design to significantly reduce power dissipation. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports data flow in transparent, latched, or clocked modes via D-type latches and flip-flops. It features a flow-through architecture optimized for PCB layout and includes equivalent 25-Ω series resistors at the B-port outputs to reduce overshoot and undershoot without external components.

Feature Summary

• Combines D-type latches and D-type flip-flops to enable operation in transparent, latched, or clocked modes
• B-port outputs include equivalent 25-Ω series resistors to minimize signal overshoot and undershoot
• Flow-through architecture optimizes printed circuit board layout efficiency
• Maintains high-impedance state during power-up and power-down sequences

Applications

• High-speed data transfer between memory modules and processors
• Clock distribution networks requiring precise timing control
• Buffering applications in complex digital logic systems

Procurement Notes

Verify that the specific ordering suffix matches the required package type and environmental compliance standards.
