LOGIC GATES AND INVERTERS
SN74ACT245NS is a octal bus transceiver with 3-state outputs from Texas Instruments. It is a 20-pin small-outline package (SOP20). Description: The SN74ACT245NS is an octal bus transceiver with 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. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated. Features: * High-speed operation: tpd = 10 ns (typical) * Low power consumption: ICC = 4 mA (max) * Outputs source/sink 24 mA * TTL-compatible inputs * Outputs in high-impedance state when OE is high Applications: * Data transmission between two buses * Data transmission between two systems * Data buffering * Data isolation (For reference only)
