SN74LV273APWRE4

Flip Flops Overview

The SN74LV273APWRE4 is an octal D-type flip-flop from the Texas Instruments LV logic series, housed in a TSSOP-20 package. It operates within a supply voltage range of 2 V to 5.5 V and supports mixed-mode port operation. The device features a propagation delay of 22.1 ns, with output drive capabilities of -12 mA (high) and 12 mA (low). It functions across an industrial temperature range of -40°C to +125°C.

Flip Flops Feature Summary

• Supports mixed-mode voltage operation across all ports
• Includes direct clear functionality for synchronous data control
• Provides latch performance exceeding JESD 17 standards

Flip Flops Applications

• Power substation control systems
• I/O modules in analog PLC/DCS inputs
• Human-machine interface (HMI) devices
• Flow metering instrumentation
• Patient monitoring equipment

Flip Flops Procurement Notes

Verify the specific suffix RE4 indicates tape and reel packaging configuration distinct from non-reel variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the TSSOP-20 footprint matches the target PCB layout requirements exactly.

Flip Flops Selection Notes

Select this component when mixed-mode voltage compatibility is required alongside standard CMOS input characteristics. The LV series offers lower power consumption compared to HC counterparts while maintaining adequate drive strength for general digital interfacing tasks in industrial environments.

Flip Flops Part Context

This part belongs to the SN74LV273A family of octal D-type flip-flops. It shares functional similarities with SN74LV273ADBR and SN74LV273ADWR but differs in physical packaging and shipping format. The PWRE4 designation specifically identifies the TSSOP-20 form factor with reel-based distribution.

Flip Flops Replacement Considerations

SN74LV273ADBR serves as a pin-compatible alternative utilizing SSOP-20 packaging.
