SN74ALVC244PWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVC244PWRE4 is an octal buffer and line driver with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features two independent 4-bit drivers with separate output-enable inputs. The device provides ±24 mA output drive at 3.3 V and achieves a maximum propagation delay of 2.8 ns at 3.3 V. It is housed in a 20-pin TSSOP package and supports an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'E4' corresponds to lead-free and RoHS-compliant material composition as defined in the manufacturer's documentation. Confirm that the tape and reel packaging details match the required manufacturing equipment specifications. Ensure the component status is listed as active production data before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring operation between 1.65 V and 3.6 V with high-speed signal integrity. The ALVC logic family offers faster switching speeds compared to standard LVC variants. Verify that the 20-pin TSSOP package dimensions fit the available PCB footprint and that the thermal impedance characteristics are suitable for the intended enclosure environment.
