www.DataSheet4U.com MOTOROLA SEMICONDUCTOR TECHNICAL DATA Dual Supply Octal Translating Transceiver with 3-State Outputs The 74LVX4245 is a 24 pin dual supply, octal translating transceiver that is designed to interface between a 5V bus and a 3V bus in a mixed 3V/5V supply environment such as laptop computers using a 3.3V CPU and 5V LCD display.

The A port interfaces with the 5V bus; the B port interfaces with the 3V bus.

The Transmit/Receive (T/R) input determines the directi

* will result. In actuality the VCCB can be powered “slightly” before the VCCA without the current penalty, but this “setup time” is dependent on the power

* up ramp rate of the VCC pins. With a ramp rate of approximately 50mV/ns (50V/µs) a 25ns setup time was observed (VCCB DataSheet 4 U .com
