SN74ABT640NSR Description

Short technical summary and product information.

The SN74ABT640NSR is an octal bus transceiver manufactured by Texas Instruments, designed for asynchronous communication between data buses. This device transmits inverted data and features 3-state outputs, allowing for effective bus isolation when disabled.

 

Key electrical specifications include a wide operating voltage range of 4.5V to 5.5V, with high-drive outputs capable of sourcing -32mA and sinking 64mA. The input and output types are TTL compatible. The transceiver operates reliably within an ambient temperature range of -40°C to 85°C.

 

This component utilizes an EPIC-IIB BiCMOS design, significantly reducing power dissipation. It offers over-voltage tolerant inputs and partial power-down capabilities (Ioff). ESD protection exceeds 2000V per MIL-STD-883, Method 3015, and latch-up performance exceeds 500mA per JEDEC Standard JESD-17.

 

The SN74ABT640NSR is available in a 20-SOIC surface mount package. Its design is suitable for applications requiring high-speed data transfer and reliable bus interfacing.
