74VCX162245MTDX

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74VCX162245MTDX is a low-voltage, 16-bit dual-supply translating transceiver housed in a 48-pin TSSOP package. It facilitates bidirectional data transfer between buses operating at different voltage levels, specifically supporting translation from lower potential rails (1.65V to 2.7V) to higher potential rails (2.3V to 3.6V). The device features non-inverting logic with three-state outputs and utilizes patented Quiet Series noise reduction circuitry to minimize electromagnetic interference.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual-supply architecture enabling true signal translation between disparate voltage domains
• Patented Quiet Series technology for reduced noise and EMI emissions
• Bidirectional interface capability supporting live insertion and withdrawal operations

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between buses at different supply voltages
• Low-voltage system bus interfacing
• Data routing in portable electronic devices

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin carefully, as Fairchild Semiconductor has undergone corporate restructuring and its logic products are now distributed under ON Semiconductor. Confirm that the specific suffix 'MTDX' corresponds to the required tape-and-reel packaging configuration rather than bulk or other variants. Ensure RoHS compliance status matches project requirements, as historical batches may vary.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring level shifting between 1.8V/2.5V and 3.3V domains without external translators. It is suitable for applications demanding low power consumption and high noise immunity. Consider the 48-TSSOP footprint during PCB layout. Verify that the VCCB supply remains less than or equal to VCCA to ensure proper device operation and prevent latch-up issues.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the VCX family of low-voltage translating transceivers designed for mixed-voltage environments. It serves as a functional equivalent to standard 74-series 16245 devices but operates at significantly lower supply voltages. The series is characterized by its ability to bridge voltage gaps while maintaining signal integrity through advanced noise suppression techniques.
