74LV245
Datasheet
General description
The 74LV245 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT245.
The 74LV245 is an octal transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. The 74LV245 features an output enable (OE) input for easy cascading and a send/receive (DIR) input for direction control. OE controls the outputs so that the buses are effectively isolated.
Features
- Wide operating voltage: 1.0 to 5.5 V
- Optimized for low voltage applications: 1.0 to 3.6 V
- Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V
- Typical V OLP (output ground bounce) < 0.8 V at VCC = 3.3 VT amb = 25°C
- Typical V OHV (output V OH undershoot) > 2 V at VCC = 3.3 VT amb = 25°C
- Output capability: bus driver
- ICC category: MSI
