Texas Instruments SN74ABT646 Octal Bus Transceivers And Registers With 3-State Outputs SN74ABT646DBR

The SN74ABT646 is an octal bus transceiver and register with 3-state outputs, designed using Texas Instruments' EPIC-II BiCMOS technology, which significantly reduces power dissipation. It features ESD protection exceeding 2000 V per MIL-STD-883C and latch-up performance that exceeds 500 mA per JEDEC Standard JESD-17. The device supports high-drive outputs with a maximum output current of -32 mA for high and 64 mA for low. This component allows for multiplexed transmission of data from the input bus or internal registers, with control inputs for output enable (OE) and direction (DIR). It can operate in various modes, including real-time data transfer and isolation. The SN74ABT646 is characterized for operation from -40¬8C to 85¬8C and is available in multiple package options, including a 24-pin shrink small-outline package (DB), which offers a compact footprint suitable for space-constrained applications.
