CD74HC112PWT

Overview

The CD74HC112PWT is a dual J-K flip-flop from Texas Instruments' 74HC logic family, housed in a 16-TSSOP package. It operates within a supply voltage range of 2V to 6V and supports clock frequencies up to 60MHz. The device features negative-edge triggering with independent preset (/PRE) and clear (/CLR) inputs that function asynchronously. Typical propagation delay is 30ns at 6V with 50pF load. Output drive capability reaches ±5.2mA at 5V, while static current consumption remains low at approximately 4µA.

Feature Summary

• Dual independent J-K flip-flops with negative-edge clock triggering
• Asynchronous active-low preset and clear control inputs
• Wide operating voltage range supporting 2V to 6V systems
• Low power consumption with high noise immunity characteristics

Applications

• Server infrastructure timing circuits
• LED display multiplexing drivers
• Network switch control logic
• Telecommunications equipment state machines
• Motor driver interface logic

Procurement Notes

Verify the specific suffix 'PWT' corresponds to the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status matches project requirements. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity. Cross-reference manufacturer datasheets for pinout accuracy against PCB footprint designs.

Selection Notes

Select this component for applications requiring dual edge-triggered storage in compact surface-mount layouts. Compare against through-hole DIP variants if board space permits alternative packaging. Evaluate thermal performance constraints given the small package size. Consider signal integrity requirements for high-speed clock lines exceeding typical HC family limits.

Part Context

This part belongs to the extensive 74HC series of CMOS digital logic ICs produced by Texas Instruments. It shares functional compatibility with other 74HC112 variants differing primarily in package type or reel configuration. The series is widely adopted in general-purpose digital systems requiring reliable state retention and moderate switching speeds.

Replacement Considerations

CD74HC112NSR serves as a direct SOIC-16 package substitute. SN74HC112N offers a through-hole DIP-16 alternative. Verify pin compatibility and electrical specifications before substituting across different package families.
