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 V . CC 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 3.
