CD74HCT652M96

Overview

The CD74HCT652M96 is a high-speed CMOS octal-bus transceiver and register with three-state outputs. It operates on a single supply voltage ranging from 4.5V to 5.5V. The device features independent registers for A and B buses, allowing multiplexed transmission of data directly from the bus or internal storage. It provides non-inverting outputs and drives up to 15 LSTTL loads. The component supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Features independent D-type flip-flops for both A and B data buses to store real-time or stored data.
• Provides three-state outputs controlled by dedicated OEAB and OEBA pins for effective bus management.
• Includes select control pins (SAB, SBA) to switch between real-time transfer and stored data modes without decoding glitches.

Applications

• Bus-oriented memory mapping
• Clock buffering
• Bus specification conversion

Procurement Notes

Verify the specific ordering suffix against current Texas Instruments documentation, as the M96 variant may be listed as obsolete in recent package option addendums. Confirm that the SOIC-24 package and tape-and-reel format align with current manufacturing availability before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring bidirectional data flow between two eight-bit buses with optional latching capabilities. Ensure the logic family matches the system's TTL compatibility requirements, specifically verifying input voltage thresholds against the HCT specifications for reliable signal interfacing.

Part Context

This part belongs to the Texas Instruments CD74HCT652 series of high-speed CMOS logic devices. It integrates octal bus transceiver functionality with dual eight-bit registers. The design utilizes silicon-gate CMOS technology to achieve speeds comparable to LSTTL while maintaining low power consumption typical of standard CMOS integrated circuits.
