74LVC245A; 74LVCH245A Octal bus transceiver; 3-state Rev. 9 — 11 September 2018 Product data sheet 1. General description The 74LVC245A; 74LVCH245A are 8-bit transceivers featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The device features an output enable (OE) input for easy cascading and a send/receive (DIR) input for direction control. OE controls the outputs so that the buses are effectively isolated. Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices in mixed 3.3 V and 5 V applications. The 74LVCH245A bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs. 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 Inputs accept voltages up to 5.5 V High-impedance when VCC = 0 V Bus hold on all data inputs (74LVCH245A only) 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 °C 74LVC245A; 74LVCH245A Nexperia Octal bus transceiver; 3-state 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.
