SN74ABT273PW

Flip Flops Overview

The SN74ABT273PW is an octal D-type flip-flop from the Texas Instruments ABT logic series, housed in a 20-pin TSSOP surface-mount package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 150 MHz. The device features non-inverting outputs with three-state capability, providing high drive strength with low-level output currents of 64 mA and high-level output currents of -32 mA. Propagation delay is specified at 6.8 ns under standard conditions.

Flip Flops Feature Summary

• Octal D-type edge-triggered flip-flop architecture for parallel data storage
• Three-state outputs enabling direct bus interface connections
• High-speed operation supporting clock frequencies up to 150 MHz
• Low input capacitance minimizing loading effects on driving circuits

Flip Flops Applications

• Parallel-to-serial data conversion interfaces
• Register files in microprocessor-based systems
• Data buffering between asynchronous logic domains
• Timing synchronization in high-speed digital communication links

Flip Flops Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-20 package variant during sourcing. Confirm RoHS compliance status as required by project specifications. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout mismatches. Check for any recent product change notifications that may affect lead times or material composition.

Flip Flops Selection Notes

Select this component when an octal register with three-state outputs is required for 5V logic systems. The ABT series offers superior speed compared to standard 74F or 74LS families while maintaining compatible voltage levels. Consider the TSSOP package for space-constrained PCB layouts requiring surface-mount assembly techniques.

Flip Flops Part Context

This device belongs to the SN74ABT family of advanced BiCMOS logic devices. The ABT series combines the speed of Schottky TTL with CMOS low power consumption. The SN74ABT273 specifically provides eight independent D-type flip-flops with positive-edge triggering and complementary outputs for versatile digital design applications.

Flip Flops Replacement Considerations

SN74ABT273DR (SOIC-20 package), SN74ABT273N (PDIP-20 package), SN74ABT273DBR (SSOP-20 package). Verify pin compatibility and thermal characteristics when substituting different package types.
