74LVC245A 74LVCH245A Octal bus transceiver 3-state Rev. 8 28 June 2013 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 V = 0 V CC 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 C74LVC245A 74LVCH245A Nexperia Octal bus transceiver 3-state 3.
