74ABT16500CSSC

Overview

The onsemi 74ABT16500CSSC is an 18-bit universal bus transceiver featuring 3-state outputs, housed in a 56-lead SSOP package. It integrates D-type latches and flip-flops to support transparent, latched, and clocked data flow modes. The device operates within a supply voltage range of +4.5V to +5.5V and supports a maximum clock frequency of 150 MHz. Propagation delays range from 1.5 ns to 5.3 ns depending on the control path. It includes glitch-free high impedance during power cycles and non-destructive hot insertion capability.

Feature Summary

• Combines D-type latches and flip-flops for flexible transparent, latched, or clocked operation
• Flow-through architecture optimizes PCB layout efficiency
• Provides glitch-free high impedance bus loading throughout the entire power-up and power-down cycle
• Supports non-destructive hot insertion capabilities

Applications

• Universal bus transceivers requiring 18-bit data width
• Clock and data multiplexing applications
• Fanout buffer circuits for signal distribution
