SN74ALVCH16600DL

Overview

The SN74ALVCH16600DL is an 18-bit universal bus transceiver manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features 3-state outputs. The device combines D-type latches and flip-flops for transparent, latched, clocked, or clock-enable modes. Maximum propagation delay is 4 ns at 3.3 V. Output drive capability reaches ±24 mA at 3.3 V. It utilizes the SSOP-56 (DL) package and supports an operating temperature range of -40 °C to 85 °C.

Feature Summary

• Combines D-type latches and flip-flops for versatile data flow control
• Active bus-hold circuitry eliminates external pullup/pulldown resistors
• Latch-up performance exceeds 250 mA per JESD 17
• Fully specified for partial power down applications using I_OFF

Applications

• High-density data acquisition systems
