SN74F2244N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F2244N is an octal buffer and line driver from the Texas Instruments F logic series. It features eight non-inverting inputs and three-state outputs, housed in a 20-pin PDIP package. The device operates on a single supply voltage ranging from 4.5 V to 5.5 V. Key electrical characteristics include a high-level output current of -15 mA and a low-level output current of 64 mA at 5 V. Propagation delay is specified at 7 ns under 5 V conditions. The component supports through-hole mounting and functions within a temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant, as the 'N' suffix typically denotes a plastic dual-in-line package. Confirm RoHS compliance status with the manufacturer, as older F-series parts may have different environmental certifications. Ensure the operating temperature range meets system requirements, as this specific part is rated for commercial temperatures only. Cross-reference pinouts with official datasheets to prevent installation errors.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high drive capability is required, specifically noting its 64 mA low-level sink current compared to standard TTL loads. Consider the propagation delay of 7 ns for timing-sensitive designs. Evaluate the need for three-state control if bus sharing is necessary. Compare against CMOS alternatives like the HC or HCT series if lower power consumption is a priority over drive strength.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74F family of high-speed TTL logic devices. It is functionally similar to the SN74F244 but differs in polarity, being non-inverting rather than inverting. It serves as a direct replacement for other octal buffers in legacy designs requiring strong current drive capabilities.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74F244N is a functional substitute if inverting logic is acceptable. For non-inverting requirements, verify compatibility with other F-series octal buffers. Check pinout alignment before swapping with variants from different manufacturers.
