74HC245; 74HCT245  
Octal bus transceiver; 3-state  
Rev. 6 — 6 September 2021  
Product data sheet  
1. General description  
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  
.
2. Features and benefits  
Wide supply voltage range from 2.0 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 JESD22-A114F exceeds 2000 V  
MM JESD22-A115-A exceeds 200 V  
Multiple package options  
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
