SN74HCT244NE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT244NE4 is an octal buffer and line driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features low power consumption with a maximum ICC of 80µA. The device provides high-current outputs capable of driving up to 15 LSTTL loads, with ±6mA output drive at 5V. Typical propagation delay is 13ns. Inputs are TTL-voltage compatible with a maximum input current of 1µA. The component is housed in a 20-pin PDIP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

Configured as two independent 4-bit buffers or drivers with separate output-enable inputs for flexible bus management.
Outputs enter a high-impedance state when the enable input is high, preventing bus contention during multi-driver operations.
TTL-compatible inputs allow direct interfacing with standard logic families without additional level shifting.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix 'E4' corresponds to the specific lead-free and RoHS-compliant variant required for your assembly process. Confirm the package type matches the mechanical footprint constraints of your PCB design. Ensure the operating temperature range aligns with your system's environmental specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-density octal buffering with 3-state control capabilities. It is suitable for applications needing to drive multiple loads from a single source while maintaining low static power consumption. Consider the 20-pin PDIP package if through-hole mounting is preferred over surface-mount alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx4HCT244 family of octal buffers and line drivers. The family includes variants such as SN74HCT244N and SN74HCT244DWR, which share identical electrical characteristics but differ in packaging options like SOIC or SSOP. The NE4 suffix specifically denotes the lead-free PDIP version produced by Texas Instruments.
