74AC74PC

Overview

The onsemi 74AC74PC is a dual D-type edge-triggered flip-flop belonging to the 74AC logic series. It features differential outputs with inverting and non-inverting polarity options, housed in a PDIP-14 through-hole package. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40 °C to +85 °C. Key electrical specifications include a propagation delay of 14 ns, a high-level output current of -24 mA, and a low-level output current of 24 mA. This component is currently listed as obsolete.

Feature Summary

Dual D-type positive-edge triggered flip-flops with single-ended inputs
Differential outputs providing both inverting and non-inverting signals
CMOS technology ensuring low static power consumption
High drive capability for direct load interfacing

Applications

Parallel-to-serial data conversion circuits
Shift register construction
Timing and synchronization logic modules
General-purpose digital storage elements

Procurement Notes

This component is officially designated as obsolete by the manufacturer. Availability is restricted to surplus or secondary market channels. Verify RoHS compliance details directly with suppliers. Ensure the source document matches the specific part number to confirm authenticity and condition before acquisition.

Selection Notes

Select this part when a through-hole PDIP-14 package is required for dual D-type flip-flops. It suits designs needing 2 V to 6 V operation and moderate speed performance. Consider surface-mount alternatives like MC74AC74DR2G if PCB space constraints exist. Verify input compatibility with existing logic levels.

Part Context

Part of the 74AC family offering improved speed over standard 74LS counterparts. Provides dual independent flip-flops in a single 14-pin package. Designed for general-purpose digital applications requiring reliable state storage and edge-triggered data transfer capabilities.
