74LVC245A 74LVCH245A Octal bus transceiver 3-state Rev. 10 5 August 2020 Product data sheet 1. General description The 74LVC245A 74LVCH245A 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 can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. This device is fully specified for partial power down applications using I . The I circuitry OFF OFF disables the output, preventing the potentially damaging backflow current through the device when it is powered down. 2. Features and benefits 5 V tolerant inputs/outputs for interfacing with 5 V logic Wide supply voltage range from 1.2 V to 3.6 V CMOS low-power consumption Direct interface with TTL levels Overvoltage tolerant inputs to 5.5 V Bus hold on all data inputs (74LVCH245A only) I circuitry provides partial Power-down mode operation OFF Complies with JEDEC standard: JESD8-7A (1.65 V to 1.95 V) JESD8-5A (2.3 V to 2.7 V) JESD8-C/JESD36 (2.7 V to 3.6 V) ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115B exceeds 200 V CDM JESD22-C101E exceeds 1000 V Specified from -40 C to +85 C and -40 C to +125 CNexperia 74LVC245A 74LVCH245A Octal bus transceiver 3-state 3.
