CMOS 4 x 4 Multiport Register
Description
The CD40208BMS is a 4 x 4 multiport register containing four 4-bit registers, write address decoder, two separate read address decoders, and two 3-state output buses. When the ENABLE input is low, the corresponding output bus is switched, independently of the clock, to a high impedance state. The high impedance third state provides the outputs with the capability of being connected to the bus lines in a bus organized system without the need for interface or pull-up components. When the WRITE ENABLE input is high, all data input lines are latched on the positive transition of the CLOCK and the data is entered into the word selected by the write address lines. When WRITE ENABLE is low, the CLOCK is inhibited and no new data is entered. In either case, the contents of any word may be accessed via the read address lines independent of the state of the CLOCK input. The CD40208BMS types are supplied in hermetic 24-lead dual-in-line ceramic packages (D and F suffixes), 24-lead dual-in-line plastic packages (E suffix), 24-lead ceramic flat packages (K suffix), and in chip form (H suffix). The CD40208BMS is supplied in these 24-lead outline packages: Braze Seal DIP Ceramic Flatpack HNZ H4P
