OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS
SN74AHCT245NSR is a high-speed octal bus transceiver from Texas Instruments. It is a 20-pin SOP package. Description: The SN74AHCT245NSR is a high-speed octal bus transceiver 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 operation: tpd = 11 ns (typ) at VCC = 5 V Low power consumption: ICC = 4 μA (max) Inputs and outputs are TTL-compatible Bus hold on data inputs eliminates the need for external pullup/pulldown resistors Outputs can be wired-ANDed Outputs can be connected to other open-collector outputs to implement active-low busses Input clamping diodes Outputs source/sink 24 mA Applications: Data transmission between two buses Data transmission between two systems Data transmission between two processors Data transmission between two microcontrollers (For reference only)
