CD74ACT273M96

Overview

The CD74ACT273M96 is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the ACT logic series. It features a master reset function and non-inverting outputs. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 85 MHz. It exhibits a propagation delay of 13.5 ns at 5 V with a 50 pF load. The device provides high-level and low-level output currents of 24 mA each. It is housed in a 20-pin SOIC package and functions across an industrial temperature range from -55 °C to +125 °C.

Feature Summary

• Integrates eight independent D-type flip-flops with positive edge triggering for parallel data storage.
• Includes a dedicated master reset input that asynchronously clears all flip-flop outputs to a low state.
• Delivers strong drive capability through symmetrical 24 mA source and sink output currents.

Applications

• Parallel-to-serial data conversion circuits
• Register stages in digital signal processing systems
• State machine implementation in control logic

Procurement Notes

Verify the specific manufacturer origin, as historical records indicate production by Harris Semiconductor prior to acquisition. Confirm RoHS compliance status against current datasheets, as older batches may not meet modern environmental standards. Ensure the SOIC-20 package dimensions align with PCB footprint requirements. Validate the ACT series specifications against system voltage constraints.

Selection Notes

Select this component when a 5 V logic interface is required alongside high-speed performance characteristics. The ACT series offers superior switching speeds compared to standard HC or HCT families. Consider the 24 mA output drive strength for direct interfacing with heavier loads without additional buffering. Verify compatibility with existing board space constraints due to the surface-mount SOIC form factor.

Part Context

This part belongs to the CD74ACT273 family of octal D-type flip-flops. It serves as a high-speed alternative to lower-performance logic families like HC or HCT. The device is designed for applications requiring rapid data latching and transfer in complex digital architectures. It maintains pinout compatibility with other 74-series octal registers while offering enhanced electrical performance metrics.
