Description
74HC Family,
High-Speed CMOS Logic
Operating Voltage: 2 to 6 V
Compatibility: Input CMOS, Output CMOS
The 74HC245, 74HCT245 is an 8-bit transceiver with 3-state outputs. The device features an output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
Mixed 5 V and 3.3 V applications
Improve the current drive and voltage level of signals

Wide supply voltage range
Low propagation delay
Registered options
TTL input options
Source termination resistor options
Overvoltage tolerant options
Bus-hold options
Key applications
Telecomunications infrastructure
Industrial control
Test systems
