CD4099 - 8 bit Addressable Latch IC
The CD4099 8-bit addressable latch IC is a serial-input, parallel-output storage register that can perform a variety of functions. Data are inputted to a particular bit in the latch when that bit is addressed (by means of input A0, A1, A2) and when WRITE DISABLE is at a low level. When WRITE DISABLE is high, data entry is inhibited; however, all 8 outputs can be continuously read independently of WRITE DISABLE and address inputs.
A master RESET input is available, which resets all bits to a logic "0" level when RESET and WRITE DISABLE is at a high level. When RESET is at a high level, and WRITE RESET is at a low level, the latch acts as a 1-of-8 demultiplexer; the bit that is addressed has an active output that follows the data input, while all unaddressed bits are held to a logic "0" level.
The CD4099 types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).
