TECHNICAL DATA
Presettable Up/Down Counter
High-Voltage Silicon-Gate CMOS
IW4516B
The IW4516B Presettable Binary Up/Down Counter consists of four
synchronously clocked D-type flip-flops (with a gating structure to
provide T-type flip-flop capability) connected as counters. This counter
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.
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.
The IW4516B 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 terminal 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 subsequent
counting stage.
Operating Voltage Range: 3.0 to 18 V
Maximum input current of 1 µA at 18 V over full package-
temperature range; 100 nA at 18 V and 25°C
Noise margin (over full package temperature range):
1.0 V min @ 5.0 V supply
2.0 V min @ 10.0 V supply
2.5 V min @ 15.0 V supply
