CD74HC40105MTG4 Datasheet



The CD74HC40105MTG4 are high-speed silicon-gate CMOS devices that are compatible, except for “shift-out” circuitry, with the CD40105B. They are low-power rst-in-out (FIFO) “elastic” storage registers that can store 16 four-bit words. The 40105 is capable of handling input and output data at different shifting rates. This feature makes it particularly useful as a buffer between asynchronous systems. CD74HC40105MTG4 Features • Independent Asynchronous Inputs and Outputs• Expandable in Either Direction• Reset Capability• Status Indicators on Inputs and Outputs• Three-State Outputs• Shift-Out Independent of Three-State Control• Fanout (Over Temperature Range)• Wide Operating Temperature Range -55℃ to 125℃• Balanced Propagation Delay and Transition Times• Signicant Power Reduction Compared to LSTTL Logic ICs CD74HC40105MTG4 Applications • Bit-Rate Smoothing• CPU/Terminal Buffering• Data Communications• Peripheral Buffering• Line Printer Input Buffers• Auto-Dialers• CRT Buffer Memories• Radar Data Acquisition
