OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS
SN74AHC245NSR is a Octal Bus Transceiver and Register manufactured by Texas Instruments. It is a 20-pin SOP package. Description: The SN74AHC245NSR is a high-speed Octal Bus Transceiver and Register with non-inverting 3-state outputs. It is designed for asynchronous two-way communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus depending on the logic level at the direction control (DIR) input. Features: * High-Speed Performance: tpd = 11.5ns (typ.) at VCC = 5V * Low Power Consumption: ICC = 4μA (max.) * High Noise Immunity Characteristic of CMOS Devices * Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors Applications: * Microprocessor Systems * Bus Oriented Circuits * High-Speed Bi-directional Data Communication between Two Buses (For reference only)
