Manufacturer: NXP Semiconductors.


74LV245 datasheet



The 74LV245 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC245 and 74HCT245.

The device is an octal transceiver with non-inverting 3-state bus compatible outputs in both send and receive directions. A send/receive (DIR) input controls direction, and an output enable (OE) input makes easy cascading possible. PinOE controls the outputs so that the buses are effectively isolated.


1. Wide operating voltage: 1.0 V to 5.5 V

2. Optimized for low voltage applications: 1.0 V to 3.6 V

3. Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V

4. Typical output ground bounce < 0.8 V at VCC = 3.3 V and Tamb = 25 °C

5. Typical HIGH-level output voltage (VOH) undershoot: > 2 V at VCC = 3.3 V and Tamb = 25 °C
