SN74ABT540DBR Description

Short technical summary and product information.

The SN74ABT540DBR from Texas Instruments is an octal buffer and line driver designed for driving bus lines or buffer memory address registers. This device features 8 channels with 3-state outputs and TTL-compatible CMOS inputs.

 

Key electrical characteristics include an operating voltage range of 4.5V to 5.5V. It supports high drive outputs with 64mA IOL and -32mA IOH. The operating temperature range is specified from -40°C to 85°C.

 

This buffer/driver utilizes the EPIC-IIB BiCMOS design, which significantly reduces power dissipation. It offers features such as over-voltage tolerant inputs and partial power down (Ioff). ESD protection exceeds 2000V per MIL-STD-883, Method 3015.

 

The SN74ABT540DBR is available in a 20-SSOP package, suitable for surface mounting. Its design facilitates printed circuit board layout with inputs and outputs on opposite sides of the package. The 3-state control gate has active-low inputs, ensuring a high-impedance state during power up or power down when OE is tied to VCC through a pullup resistor.
