74LVC245A; 74LVCH245A Octal bus transceiver; 3-state Rev. 13 — 8 August 2023 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 IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down. 2. Features and benefits • • • • • • • • • 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) IOFF circuitry provides partial Power-down mode operation 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: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V Specified from -40 °C to +85 °C and -40 °C to +125 °C 3.

Valid for data inputs of bus hold parts only (74LVCH245A). Note that control inputs do not have a bus hold circuit. The specified sustaining current at the data input holds the input below the specified VI level. The specified overdrive current at the data input forces the data input to the opposite input state. 74LVC_LVCH245A Product data sheet All information provided in this document is subject to legal disclaimers.
