SN74HC245PWR Octal Bus Transceiver Chip Programmable Logic IC

Transceiver Chip SN74HC245PWR TSSOP-20 with 3 State Outputs Programmable Logic IC

Description

The SN74HC245PWR is an octal Bus Transceiver with 3-state outputs and designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The devices allow 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.

To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver.

12ns typical Propagation delay (tpd)
±6mA Output drive at 5V
1µA maximum Low input current
Green product and no Sb/Br

Applications

Industrial, Automation & Process Control, Signal Processing, Communications & Networking
