(25) CD 40105BE 40105 FIFO REGISTER, New, old stock (NOS ICs) DIP ICs. The CD40105BE CMOS IC is equivalent to the MC140105BE / MC140105, SGS140105BE / SGS140105, HEF140105BE / HEF140105, HCF140105BE / HCF140105, TC140105BE / TC140105, and other CD40105 CMOS equivalent ICs. The CD40105 has asynchronous inputs and outputs, and 3-state outputs. Input and output data can be shifted at different rates. In other words, you load in your data at one rate, and then as you require, you peel off your data at either the same rate or at a faster or slower rate. This is often referred to as an "elastic" register. You can easily expand them so that one 40105 dumps its output into the input of another 40105, other register or memory. And you can expand two 40105 registers to make an 8 bits x 16 words FIFO register, and four 40105 to make a 16 bits x 16 words FIFO register, etc. Most circuit designers do not need a FIFO register (First-In, First-Out register) every day. However, when you need one, you either must use an excellent FIFO register like the 40105 or at least 3 other ICs and a lot of extra wiring to perform the same FIFO register function. It pays to have an ample supply of FIFO registers in your parts bins. The CD 40105 is typically used for bit rate smoothing, CPU buffering, terminal buffering, data communications, peripheral buffering, printer input buffering, computer monitor memory buffering, autodialers, data encryption, data decryption, voice scrambling, voice descrambling, voice disguisers, audio special special effects, downconverters, upconverters, record and playback systems, security systems, key storage and key retrieval systems, data comparators, and radar data acquisition systems. Very versatile and flexible. NOTE: Later availability not guaranteed. LIMITED QUANTITY. Seller listing codes: LD061, LR097-S01, LS000-R00, MM000, CC000.
