CD74AC273M

Overview

The CD74AC273M is an octal D-type flip-flop from the Texas Instruments AC logic family, housed in a 20-pin PDIP package. It features a master reset input and non-inverting outputs. The device operates on a supply voltage range of 1.5 V to 5.5 V. Key electrical parameters include a propagation delay of 169 ns, high-level output current of -24 mA, and low-level output current of 24 mA. It supports through-hole mounting and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops per single integrated circuit.
• Master reset functionality allows simultaneous clearing of all flip-flop states via a dedicated control line.
• CMOS technology ensures compatibility with standard logic families while maintaining low static power consumption.

Applications

• Parallel-to-serial data conversion circuits
• General-purpose register storage applications
• Timing and sequencing control systems

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure the component matches the required AC logic series specifications for voltage and speed. Confirm RoHS compliance status if environmental regulations apply to the target assembly process.

Selection Notes

Select this component when an octal storage element with a global reset is required. The AC series offers a balance of speed and power suitable for general digital logic. Verify that the 1.5V to 5.5V operating range aligns with the system power supply constraints.
