SN74HC244ANSRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC244ANSRG4 is an octal buffer and line driver manufactured by Texas Instruments, belonging to the HC logic series. It features eight non-inverting inputs and outputs with three-state capability, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 2 V to 6 V, drawing a maximum static current of 8 uA and a working power current of 80 uA. Output drive capabilities include -7.8 mA at high level and 7.8 mA at low level. Propagation delay varies from 130 ns at 2 V to 22 ns at 6 V. It supports surface mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the suffix against official Texas Instruments documentation to confirm specific tape-and-reel packaging and RoHS compliance status. Ensure the ordering quantity aligns with manufacturer reel specifications. Cross-reference the datasheet revision date to guarantee compatibility with current design requirements and regulatory standards before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring eight buffered channels with three-state output control. It is suitable for applications needing operation across a wide voltage range from 2 V to 6 V. Consider its propagation delay characteristics relative to system clock speeds. Verify that the SOIC-20 package fits the available PCB footprint and thermal management constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the broader SN74HC244 family of octal buffers and line drivers. Variants within this family may differ in package types such as TSSOP or SSOP, or in performance metrics like propagation delay. The 'A' designation typically indicates improved switching speed compared to standard versions. The 'G4' suffix denotes lead-free construction and environmental compliance according to manufacturer standards.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include SN74HC244AN and SN74HC244APW. Verify pinout compatibility and electrical parameters such as output current and propagation delay before substitution. Ensure the alternative part meets the same voltage and temperature operating ranges required by the application.
