54AC164245 Datasheet Rad-hard 16-bit Transceiver

Manufacturer: STMicroelectronics

Overview: 54AC164245 Datasheet Rad-hard 16-bit transceiver 3.3 V to 5 V bidirectional level shifter Product status link.

General Description

The 54AC164245 is a rad-hard advanced high-speed CMOS, Schmitt trigger, 16-bit, bidirectional, multi-purpose transceiver with 3-state outputs and cold sparing.

Designed to be used as an interface between a 5 V bus and a 3.3 V bus in mixed 5 V/3.3 V supply systems, it achieves high-speed operations while the CMOS lowpower dissipation is kept.

All pins have cold spare buffers to change them to high impedance when VDD is tied to ground.
