SN74LV273APWG4

Flip Flops Overview

The SN74LV273APWG4 is an octal D-type flip-flop from 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 CMOS input and output types with non-inverting polarity. The device features a propagation delay of 22.1 ns, with high-level and low-level output currents rated at -12 mA and 12 mA respectively. It functions across a temperature range of -40°C to +125°C and includes one circuit configuration.

Flip Flops Procurement Notes

Verify the specific ordering suffix 'PWG4' to confirm the TSSOP-20 package variant and lead-free status. Confirm RoHS compliance details directly with the manufacturer documentation. Check current lifecycle status as some sources indicate potential obsolescence for this specific part number. Ensure the application environment stays within the specified -40°C to +125°C operating temperature range for reliable performance.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with wide voltage flexibility is required. The LV series offers lower power consumption compared to standard TTL or older CMOS families. Consider the TSSOP-20 package for surface-mount assembly constraints. Verify that the 22.1 ns propagation delay meets the timing requirements of the target digital system design.

Flip Flops Part Context

This device belongs to the SN74LV273A family of octal D-type flip-flops. It is part of Texas Instruments' broader Low-Voltage CMOS logic portfolio designed for high-speed, low-power applications. The 'G4' suffix typically denotes lead-free and RoHS-compliant manufacturing processes, aligning with modern environmental standards for electronic components.
