CD4724B-MIL数据手册TI中文资料规格书

描述 Description

CD4724B 8-bit addressable latch 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 independent 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 are 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 which follows the data input, while all unaddressed bits are held to a logic \"0\" level.
The CD4724B 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 (NSR suffix), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).
