Integrated Circuits

The SN74HC245N is an Octal Bus Transceiver with 3-state outputs, designed for asynchronous 2-way communication between data buses. The control-function implementation minimizes external timing requirements. The device allows data transmission 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.

• High-current 3-state outputs drive bus lines directly or up to 15 LSTTL loads
• Low power consumption, 80µA maximum ICC
• 12ns Typical TPD
• ±6mA Output drive at 5V
• Low input current of 1µA (maximum)

The SN74HC373N (74HC373N) is an octal transparent D-Type Latch integrated circuit with 3-state outputs.

This 8-bit latch features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads.
