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.
Features and benefits
Wide supply voltage range from 2.0 V to 6.0 V
CMOS low power dissipation
High noise immunity
Octal bidirectional bus interface
Non-inverting 3-state outputs
Input levels:
For 74HC245: CMOS level
For 74HCT245: TTL level
Complies with JEDEC standards
JESD8C (2.7 V to 3.6 V)
JESD7A (2.0 V to 6.0 V)
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
Multiple package options
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
