74ABT544D Datasheet | NXP Semiconductors

description The 74ABT544 high performance Bi CMOS device bines low static and dynamic power dissipation with high speed and high output drive. The 74ABT544 octal latched transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate latch enable (LEAB, LEBA) and output enable (OEAB, OEBA) inputs are provided for each register to permit independent control of data transfer in either direction. The outputs are guaranteed to sink 64 m A. 2. Features and benefits - bines 74ABT640 and 74ABT373 type functions in one device - 8-bit octal transceiver with D-type latch - Back-to-back registers for storage - Separate controls for data flow in each direction - Live insertion and extraction permitted - Output capability: +64 m A to - 32 m A - Power-up 3-state - Power-up reset - Latch-up protection exceeds 500 m A per JESD78B class II level A - ESD protection: - HBM JESD22-A114F exceeds 2000 V - MM JESD22-A115-A exceeds 200 V 3.
