74LVT245B 3.3 V octal transceiver with direction pin 3-state Rev. 3 30 July 2021 Product data sheet 1. General description The 74LVT245B 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. Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs 2. Features and benefits Wide supply voltage range from 2.7 to 3.6 V 3-state buffers Octal bidirectional bus interface Overvoltage tolerant inputs to 5.5 V Direct interface with TTL levels BiCMOS high speed and output drive Output capability: +64 mA/-32 mA Latch-up protection exceeds 500 mA per JEDEC Std 17 Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs No bus current loading when output is tied to 5 V bus Live insertion/extraction permitted Power-up 3-state I circuitry provides partial Power-down mode operation OFF Complies with JEDEC standard JESD8C (2.7 V to 3.6 V) ESD protection: HBM JESD22-A114E exceeds 2000 V MM JESD22-A115-A exceeds 200 V Specified from -40 C to 85 C 3.
