CD40208BMS Datasheet CMOS 4 X 4 Multiport Register

Manufacturer: Intersil (now Renesas)

Overview: CD40208BMS December 1992 CMOS 4 x 4 Multiport Register.

General 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.

Key Features

  • High Voltage Types (20V Rating) One Input and Two Output Buses Unlimited Expansion in Bit and Word Directions Data Lines have Latched Inputs 3-State Outputs Separate Control of Each Bus, Allowing Simultaneous Independent Reading of any of Four Registers on Bus A and Bus B and Independent Writing Into any of the Four Registers 100% Tested for Quiescent Current at 20V Standardized, Symmetrical Output Characteristics 5V, 10V and 15V Parame.
