SN74HCT244PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT244PWR is an octal buffer and line driver manufactured by Texas Instruments, utilizing HCT CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features eight non-inverting outputs with three-state capability, organized into two independent four-bit sections. Each section includes a separate output enable (OE) input. When OE is low, data transfers from A inputs to Y outputs; when high, outputs enter a high-impedance state. Key electrical parameters include a maximum static current of 8 µA, output drive currents of ±6 mA at 5 V, and propagation delays of 45 ns at 4.5 V and 40 ns at 5.5 V. It is housed in a TSSOP-20 surface-mount package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configured as two independent four-bit buffers or drivers with separate output enable controls for each section.
• Provides three-state outputs that transition to a high-impedance state when the output enable signal is inactive.
• Features TTL-compatible inputs allowing direct interfacing with standard logic systems.

• Bus-oriented receiver and transmitter circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package and reel packaging configuration. Confirm RoHS compliance status and ensure the operating temperature range meets system requirements. Cross-reference the manufacturer part number against official datasheets to validate pinout compatibility before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-density bus driving with low power consumption. The HCT logic family ensures compatibility with TTL-level inputs while maintaining CMOS noise immunity. Consider the TSSOP-20 package for space-constrained designs requiring surface-mount assembly.
