N74F240N,602

Buffers, Drivers, Receivers, Transceivers Overview

The N74F240N,602 is an octal inverting buffer featuring three-state outputs manufactured by NXP USA Inc. It operates within a supply voltage range of 4.5V to 5.5V and supports a commercial temperature range of 0°C to +70°C. The device provides two output enables, each controlling four outputs, with typical propagation delays of 4.3 ns at 5V. Outputs sink up to 64 mA and source up to 15 mA, utilizing a 20-pin plastic DIP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '602' against official manufacturer documentation to confirm exact packaging and environmental compliance details. Confirm availability status as this component may be subject to discontinuation or lifecycle changes. Ensure compatibility with existing PCB footprints and signal integrity requirements before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal inverting buffer with three-state control is required. Consider the 64 mA low-level output current for heavy bus loading. Verify that the 20-pin DIP package fits the target assembly constraints. Evaluate the 4.3 ns typical propagation delay against system timing budgets to ensure adequate performance margins.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74F logic family, known for fast switching speeds compared to standard TTL. The N74F240 variant specifically provides octal buffering with inversion. The 'N' suffix indicates the 20-pin plastic dual in-line package (DIP) form factor, distinguishing it from surface-mount variants like the SOIC or SSOP packages available in the same logical series.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the N74F240D (SOIC-20) and N74F240DB (SSOP-20) for pin-compatible surface mount replacements. Other generic 74F240 equivalents from different manufacturers may function identically but require verification of electrical characteristics and pinout alignment.
