74AHC245BQ-Q100X

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC245BQ-Q100X is an octal bus transceiver with 3-state outputs, housed in a DHVQFN20 (SOT764-1) package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features balanced propagation delays, Schmitt-trigger inputs, and overvoltage tolerant inputs up to 5.5 V. It includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM), along with latch-up performance exceeding 100 mA per JESD 78 Class II Level A.
