SN74ACT07BQAR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT07BQAR is a hex buffer featuring TTL-compatible inputs and open-drain outputs. It operates within a supply voltage range of 4.5V to 5.5V. The device provides continuous output drive capability of 24mA at 5V, with support for short bursts up to 75mA. Maximum propagation delay is specified at 8.3ns. It functions in an industrial temperature range from -40°C to +125°C and utilizes a 14-pin WQFN package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features six independent buffers with open-drain CMOS outputs capable of sinking current to ground while remaining high-impedance in the logical high state.
• Includes TTL-compatible CMOS inputs designed to interface directly with TTL logic devices through reduced input voltage thresholds.
• Supports driving 50Ω transmission lines and indicator LEDs, suitable for level-shifting applications using the open-drain architecture.

Buffers, Drivers, Receivers, Transceivers Applications

• Drive indicator LEDs
• Level-shift signals using open-drain outputs
• Control relays

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific BQA package designation (WQFN) against the required footprint. Confirm that the application design accommodates the open-drain nature of the outputs, requiring external pull-up resistors for high-state logic levels. Ensure thermal management aligns with the specified junction temperature limits during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a hex buffer with open-drain outputs is required for wired-AND configurations or direct LED/relay driving. The TTL-compatible inputs simplify interfacing with legacy systems. Verify that the 4.5V to 5.5V supply range matches the system power rails and that the 24mA continuous sink current meets load requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ACT07 family of hex buffers. It shares functional characteristics with other variants like the SN74ACT07PWR but differs in packaging. The BQA suffix indicates a 14-pin WQFN form factor, distinct from the TSSOP PW package. It is a standard production logic IC manufactured by Texas Instruments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ACT07PWR serves as a pin-compatible alternative utilizing a TSSOP-14 package instead of the WQFN-14 configuration. Both parts share identical electrical specifications and functionality.
