CD40108BMS
CMOS 4 x 4 Multiport Register
December 1992
Features
Description
• High Voltage Type (20V Rating)
The CD40108BMS 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.
• Four 4-Bit Registers
• 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
• CD40108BMS is Pin-Compatible with Industry Type
MC14580
• Standardized Symmetrical Output Characteristics
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 CD40108BMS is supplied in these 24-lead outline packages:
• 100% Tested for Quiescent Current at 20V
• Maximum Input Current of 1µA at 18V Over Full Package Temperature Range; 100nA at 18V and +25oC
• Noise Margin (Over Full Package/Temperature Range)
- 1V at VDD = 5V
- 2V at VDD = 10V
- 2.5V at VDD = 15V

1. All voltages referenced to device GND.
2. The parameters listed on Table 3 are controlled via design or process and are not directly tested. These parameters are characterized
on initial design release and upon design changes which would affect these characteristics.
3. CL = 50pF, RL = 200K, Input TR, TF < 20ns.
4. CL = 50pF, RL = 1K, Input TR, TF < 20ns.
5. If more than one unit is cascaded, TRCL should be made less than or equal to the sumof the transition time and the fixed propagation
delay of the output of the driving stage for the estimated capacitive load.
