CMOS Presettable Up/Down Counters
Features
• High Voltage Types (20V Rating)
• CD4510BMS - BCD Type
CD4510BMS Presettable BCD Up/Down Counter and the
CD4516BMS Presettable Binary Up/Down counter consist of
four synchronously clocked D-type flip-flops (with a gating
structure to provide T-type flip-flop capability) connected as
counters. These counters can be cleared by a high level on
the RESET line, and can be preset to any binary number
present on the jam inputs by a high level on the PRESET
ENABLE line. The CD4510BMS will count out of non-BCD
counter states in a maximum of two clock pulses in the up
mode, and a maximum of four clock pulses in the down mode.
• CD4516BMS - Binary Type
• Medium Speed Operation
- fCL = 8MHz Typ. at 10V
• Synchronous Internal Carry Propagation
• Reset and Preset Capability
• 100% Tested for Quiescent Current at 20V
• 5V, 10V and 15V Parametric Ratings
If the CARRY IN input is held low, the counter advances up or
down on each positive-going clock transition. Synchronous
cascading is accomplished by connecting all clock inputs in
parallel and connecting the CARRY OUT of a less significant
stage to the CARRY IN of a more significant stage.
• Standardized Symmetrical Output Characteristics
• Maximum Input Current of 1µA at 18V Over Full Pack-
o
age Temperature Range; 100nA at 18V and +25 C
The CD4510BMS and CD4516BMS can be cascaded in the
ripple mode by connecting the CARRY OUT to the clock of
the next stage. If the UP/DOWN input changes during a ter-
minal count, the CARRY OUT must be gated with the clock,
and the UP/DOWN input must change while the clock is
high. This method provides a clean clock signal to the sub-
sequent counting stage. (See Figures 13, 14.)
• Noise Margin (Over Full Package/Temperature Range)
- 1V at VDD = 5V
- 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”
These devices are similar to types MC14510 and MC14516.
