74AHC245BQ

74AHC245; 74AHCT245 Octal bus transceiver; 3-state Rev. 6 — 3 July 2020 Product data sheet 1. General description The 74AHC245; 74AHCT245 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 are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments. 2. Features and benefits Wide supply voltage range from 2.0 V to 5.5 V Balanced propagation delays All inputs have Schmitt-trigger action Overvoltage tolerant inputs to 5.5 V High noise immunity CMOS low power dissipation Input levels: For 74AHC245: CMOS level For 74AHCT245: TTL level ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V CDM JESD22-C101E exceeds 1000 V Latch-up performance exceeds 100 mA per JESD 78 Class II Level A Multiple package options Specified from -40 °C to +85 °C and from -40 °C to +125 °C 3.
