4-Bit Bus Buffer/Separator
Description
The CDP1857C is a 4-bit CMOS non-inverting bus separator designed for use in CDP1800-series microprocessor systems.
It can be controlled directly by a 1800-series microprocessor without the use of additional components.
The CDP1857 is designed for use as a bus buffer or separator between the 1800-series microprocessor data bus and I/O devices.
It provides a chip-select (CS) input signal which, when high (1), enables the bus-separator three-state output drivers.
The direction of data flow, when enabled, is controlled by the MRD input signal.
In the CDP1857, when MRD = 1, it enables the three-state bus drivers (DB0-DB3) and transfers d...
