74LCX16652MTD

Buffers, Drivers, Receivers, Transceivers Overview

The 74LCX16652MTD is a low-voltage transceiver and register featuring sixteen non-inverting bidirectional bus transceivers with 3-STATE outputs. It supports multiplexed transmission of data directly from the input bus or from internal registers. The device operates within a supply voltage range of 2.3V to 3.6V and provides 5V tolerant inputs and outputs, enabling interfacing with 5V signal environments. Fabricated using advanced CMOS technology, it achieves high-speed operation while maintaining low power dissipation.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering code suffix 'MTD' corresponds to the 56-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide. Confirm the specific revision status and RoHS compliance details directly with the manufacturer or authorized distributor documentation prior to procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring bidirectional data buffering with registered storage capabilities in a low-voltage environment. Ensure the design accommodates the 2.3V–3.6V VCC operating range and utilizes the 5V tolerant I/Os for compatibility with legacy 5V buses. Verify that the TSSOP-56 package dimensions fit the PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the LCX family of low-voltage CMOS logic devices. It is manufactured by Fairchild Semiconductor (now onsemi). The device integrates both transceiver and register functions into a single 56-pin package, serving as a versatile interface solution for high-density digital systems requiring data isolation and storage.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check datasheets for other 74LCX16652 variants such as the SSOP package version (74LCX16652MEA) for pin-compatible alternatives. Verify electrical characteristics against similar parts from other manufacturers like NXP or Texas Instruments if sourcing from different suppliers.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle live insertion?

The device supports live insertion/withdrawal. To ensure the high-impedance state during power up or down, OE should be tied to VCC and OE tied to GND through a resistor.

What is the maximum propagation delay at 3.3V?

The maximum propagation delay (tPD) is 5.7 ns when VCC is 3.3V.
