Presettable synchronous 4-bit binary
up/down counter
Product specification
74HC/HCT193
(1) Clear overrides load, data and
count inputs.
(2) When counting up the count down
clock input (CPD) must be HIGH,
when counting down the count up
clock input (CPU) must be HIGH.
Sequence
Clear (reset outputs to zero);
load (preset) to binary thirteen;
count up to fourteen, fifteen,
terminal count up, zero, one
and two;
count down to one, zero,
terminal count down, fifteen,

(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3V; VI = GND to 3 V.
Fig.10 Waveforms showing the master reset input (MR) pulse width, MR to Qn propagation delays, MR to CPU,
CPD removal time and output transition times.
The shaded areas indicate when the input is permitted to
change for predictable output performance.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3V; VI = GND to 3 V.
Fig.11 Waveforms showing the data input (Dn) to parallel load input (PL) set-up and hold times.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3V; VI = GND to 3 V.
Fig.12 Waveforms showing the data input (Dn), parallel load input (PL) and the master reset input (MR) to the
terminal count outputs (TCU, TCD) propagation delays.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3V; VI = GND to 3 V.
