74HC40105D - 4-bit x 16-word FIFO register

Download the 74HC40105D datasheet PDF. This datasheet also covers the 74HC40105 variant, as both devices belong to the same 4-bit x 16-word fifo register family and are provided as variant models within a single manufacturer datasheet.

General Description

The 74HC40105 is a first-in/first-out (FIFO) "elastic" storage register that can store 16 4-bit words.

It can handle input and output data at different shifting rates.

This feature makes it particularly useful as a buffer between asynchronous systems.

Key Features

  • Independent asynchronous inputs and outputs.
  • Expandable in either direction.
  • Reset capability.
  • Status indicators on inputs and outputs.
  • 3-state outputs.
  • CMOS input levels.
  • Complies with JEDEC standard JESD7A.
  • ESD protection:.
  • HBM JESD22-A114F exceeds 2000 V.
  • MM JESD22-A115-A exceeds 200 V.
  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C 3. Ordering information Table 1. Order.

74HC40105 4-bit x 16-word FIFO register Rev. 5 — 19 April 2019 Product data sheet 1. General description The 74HC40105 is a first-in/first-out (FIFO) "elastic" storage register that can store 16 4-bit words. It can handle input and output data at different shifting rates. This feature makes it particularly useful as a buffer between asynchronous systems. Each word position in the register is clocked by a control flip-flop, which stores a marker bit. A logic 1 signifies that the data at that position is filled and a logic 0 denotes a vacancy in that position. The control flip-flop detects the state of the preceding flip-flop and communicates its own status to the succeeding flip-flop.
