74LVC2952APW,112

Overview

The NXP 74LVC2952APW,112 is an octal non-inverting registered transceiver housed in a TSSOP24 package. It operates on a supply voltage range of 1.2 V to 3.6 V with inputs accepting voltages up to 5.5 V. The device features two 8-bit back-to-back registers for bidirectional data storage between buses A and B. Data is latched on the rising edge of the clock when clock enable is low. Outputs are 3-state controlled by separate output enable inputs. It complies with JEDEC standards and offers ESD protection exceeding 2000 V (HBM) and 200 V (MM).

Feature Summary

• Octal registered transceiver architecture with bidirectional bus capability.
• 5 V tolerant inputs and outputs for mixed voltage interfacing.
• Dual independent clocking and control for separate A-to-B and B-to-A data paths.

Applications

• Mixed 3.3 V and 5 V logic environments requiring level translation.
• Bidirectional data buffering between microprocessors and peripheral devices.
• System architectures utilizing dual-port memory interfaces.

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP24 package variant. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for any product change notifications regarding pinout or electrical characteristics updates before finalizing design integration.

Selection Notes

Select this component for applications requiring high-speed bidirectional data transfer with registered storage. Ensure the operating voltage falls within the 1.2 V to 3.6 V range. Consider the 5 V tolerance feature if interfacing directly with legacy 5 V logic systems without additional level shifters.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices. It functions as an octal registered transceiver, distinct from unregistered transceivers like the 74LVC245. The APW suffix denotes the plastic thin shrink small outline package with 24 leads.

Replacement Considerations

Public confirmed substitute: 74LVC2952ADB (SSOP24 package).
