SN74S140DR

Inverter Gates Overview

The SN74S140DR is a Schottky TTL logic component manufactured by Texas Instruments, housed in a 16-pin SOIC surface-mount package. It functions as a dual four-input positive NAND gate with an integrated 50-ohm line driver. The device operates within a standard voltage range of 4.75 V to 5.25 V and supports a propagation delay of 8 ns at a capacitive load of 15 pF. Designed for high-speed digital applications, it provides robust signal transmission capabilities suitable for demanding electronic environments.

Inverter Gates Procurement Notes

Verify the specific suffix 'DR' confirms the tape-and-reel packaging format upon ordering. Confirm that the required operating temperature range aligns with commercial specifications. Ensure design compatibility with standard 5V TTL logic levels before finalizing procurement decisions.

Inverter Gates Selection Notes

Select this component when both high-speed NAND logic operations and integrated line driving are required within a single package. Consider the 50-ohm internal termination for applications needing controlled impedance without external components. Evaluate the SOIC footprint constraints against available board space requirements.

Inverter Gates Part Context

This part belongs to the Texas Instruments SN74S series, representing Schottky TTL logic family devices known for superior speed compared to standard variants. The SN74S140 specifically combines logical gating with transmission line driving, distinguishing it from basic logic gates or standalone drivers within the broader product portfolio.

Inverter Gates Replacement Considerations

Consult official substitution guides for parameter-equivalent alternatives. Verify pinout compatibility and electrical characteristics before replacing existing inventory.
