SN74LVC32245ZKER Datasheet PDF - TI

The SN74LVC32245ZKER is a 32-bit Bus Transceiver with 3-state outputs. The non-inverting bus transceiver is designed for 1.65 to 3.6V VCC operation. It is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements. This device can be used as four 8-bit transceivers, two 16-bit transceivers or one 32-bit transceiver. It 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 input. The output-enable (OE)\ input can be used to disable the device so that the buses are effectively isolated. Inputs can be driven from either 3.3/5V devices. This feature allows the use of this device as translators in a mixed 3.3/5V system environment. This device is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

● IOFF Supports partial-power-down mode operation

● Support mixed-mode signal operation on all ports

● 4ns at 3.3V Propagation delay (tpd)

● <0.8V at VCC = 3.3V, TA = 25°C VOLP (output ground bounce)

● >2V at VCC = 3.3V, TA = 25°C VOHV (output VOH undershoot)

● Green product and no Sb/Br
