SN74LVCZ16245A Datasheet | Texas Instruments

description /ordering information GND 15 2B3 16 34 GND 33 2A3 This 16-bit (dual-octal) noninverting bus transceiver is designed for 2.7-V to 3.6-V VCC operation. The SN74LVCZ16245A is designed for asynchronous munication between data buses. The control-function implementation minimizes external timing requirements. 2B4 17 VCC 18 2B5 19 2B6 20 GND 21 2B7 22 2B8 23 2DIR 24 32 2A4 31 VCC 30 2A5 29 2A6 28 GND 27 2A7 26 2A8 25 2OE This device can be used as two 8-bit transceivers or one 16-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 (DIR) 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-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment. When VCC is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5 V, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
