74AC273MTC

Overview

The MC74AC273MTC is an octal D-type flip-flop from the onsemi 74AC logic series, housed in a TSSOP-20 surface-mount package. It features eight edge-triggered D flip-flops with individual data inputs and Q outputs, sharing a common buffered clock (CP) and master reset (MR). The device operates within a supply voltage range of 2 V to 6 V, supporting single-ended inputs and outputs. Key electrical parameters include a propagation delay of 13 ns, high-level output current of -24 mA, and low-level output current of 24 mA. It functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Contains eight edge-triggered D-type flip-flops for parallel data storage
• Includes a buffered asynchronous master reset input to clear all flip-flops simultaneously
• Features a buffered common clock input for synchronized data loading

Applications

• Data buffering for MOS microprocessor systems
• Memory interface circuits requiring parallel data latching
• General-purpose digital logic applications involving octet data transfer

Procurement Notes

Verify the specific suffix 'MTC' corresponds to the TSSOP-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering part number matches the exact logic family (AC vs ACT) required for voltage compatibility. Cross-reference datasheet revisions to confirm pinout consistency before integration into new designs.

Selection Notes

Select this component for applications requiring fast switching speeds and moderate drive capability within a wide voltage range. The AC series offers faster performance than HC variants but requires careful attention to signal integrity due to higher slew rates. Compare against the 74ACT273 if TTL-compatible input thresholds are necessary instead of standard CMOS levels. Evaluate thermal management requirements based on the TSSOP-20 package's thermal characteristics.

Part Context

This component belongs to the 74AC273 family of octal D-type flip-flops manufactured by onsemi. It is functionally equivalent to other industry-standard octal flip-flops but utilizes onsemi's specific AC process technology. The device serves as a fundamental building block for sequential logic circuits, providing reliable data storage and synchronization capabilities in digital systems.

Replacement Considerations

Direct substitutes include MC74AC273DWR2G and MC74AC273DTR2G from onsemi, which share identical logical functionality but differ in packaging (SOIC-WB vs TSSOP). Other manufacturers may offer cross-compatible parts such as the SN74AC273, though pinout and electrical specifications must be verified against the original datasheet.
