Overview
The SN74ACT240DGSR is an octal buffer and line driver from the Texas Instruments ACT logic family, housed in a 20-pin VSSOP package. It operates within a supply voltage range of 4.5V to 5.5V. The device features two independent 4-bit sections with separate output-enable inputs. Outputs are three-state and inverted. Key electrical parameters include a maximum propagation delay of 8.5ns at 5V, high-level output current of -24mA, and low-level output current of 24mA. It supports input voltages up to 5.5V and is TTL-compatible.
Feature Summary
- Balanced CMOS push-pull outputs provide similar sourcing and sinking capabilities for improved signal integrity.
- Separate output-enable inputs allow independent control of two 4-bit buffer sections.
- Inputs accept voltages up to 5.5V, ensuring compatibility with standard logic levels.
Applications
- Smartphone handset circuits
- Network switch interfaces
- Health and fitness wearable devices
Procurement Notes
Verify the specific ordering suffix DGSR corresponds to the VSSOP-20 package variant. Confirm the active production status and lead-free material specifications via the official TI Package Option Addendum. Ensure the operating temperature range meets the design requirements before finalizing procurement.
Selection Notes
Select this component when designing systems requiring octal bus drivers with inverted logic and three-state outputs. The ACT series offers faster switching speeds compared to standard LS or HC families. Consider the VSSOP package size constraints and thermal dissipation characteristics relative to other available packages like SOIC or TSSOP.
Part Context
This part belongs to the SNx4ACT240 family of octal buffers and line drivers. The 'SN74' prefix indicates commercial grade availability, while 'ACT' denotes the advanced CMOS technology. The 'DGSR' suffix specifies the VSSOP package type and tape-and-reel shipping configuration.

FAQ
How does the device handle unused inputs?
All unused inputs must be held at VCC or GND to ensure proper device operation and prevent undefined states.
What is the function of the output-enable pins?
When the output-enable (OE) pin is low, the device passes inverted data from the A inputs to the Y outputs. When OE is high, the outputs enter a high-impedance state.
