CMOS Presettable Up/Down Counters

(Dual Clock With Reset)

December 1992

Features

Description

• CD40192BMS - BCD Type

• CD40193BMS - Binary Type

• High Voltage Type (20V Rating)

CD40192BMS Presettable BCD Up/Down Counter and the

CD40193BMS Presettable Binary Up/Down Counter each con-

sist of 4 synchronously clocked, gated “D” type ﬂip-ﬂops con-

nected as a counter. The inputs consist of 4 individual jam lines,

a PRESET ENABLE control, individual CLOCK UP and

CLOCK DOWN signals and a master RESET. Four buffered Q

signal outputs as well as CARRY and BORROW outputs for

multiple-stage counting schemes are provided.

• Individual Clock Lines for Counting Up or Counting

Down

• Synchronous High-Speed Carry and Borrow Propaga-

tion Delays for Cascading

The counter is cleared so that all outputs are in a low state by a

high on the RESET line. A RESET is accomplished asynchro-

nously with the clock. Each output is individually programmable

asynchronously with the clock to the level on the corresponding

jam input when the PRESET ENABLE control is low.

• Asynchronous Reset and Preset Capability

• Medium Speed Operation

- fCL = 8MHz (typ.) at 10V

• 5V, 10V and 15V Parametric Ratings

• Standardize Symmetrical Output Characteristics

• 100% Tested for Quiescent Current at 20V

The counter counts up one count on the positive clock edge of

the CLOCK UP signal provided the CLOCK DOWN line is high.

The counter counts down one count on the positive clock edge

of the CLOCK DOWN signal provided the CLOCK UP line is

high.

• Maximum Input Current of 1µA at 18V Over Full Pack-

age Temperature Range; 100nA at 18V and +25^oC

• Noise Margin (Over Full Package/Temperature Range)

- 1V at VDD = 5V

The CARRY and BORROW signals are high when the counter

is counting up or down. The CARRY signal goes low one-half

clock cycle after the counter reaches its maximum count in the

count-up mode. The BORROW signal goes low one-half clock

cycle after the counter reaches its minimum count in the count-

down mode. Cascading of multiple packages is easily accom-

plished without the need for additional external circuitry by tying

the BORROW and CARRY outputs to the CLOCK DOWN and

CLOCK UP inputs, respectively, of the succeeding counter

package.

- 2V at VDD = 10V

- 2.5V at VDD = 15V

• Meets All Requirements of JEDEC Tentative Standard

No. 13B, “Standard Speciﬁcations for Description of

‘B’ Series CMOS Devices”

Applications
