7.2.49 4050 (Hex BUFFER)
This device contains six independent BUFFER/non-inverting gates.
Logic function:
BUFFER gate truth table:
7.2.50 4060 (14-Stage Binary Counter & Osc)
The HEF4060B is a 14-stage ripple-carry binary counter/divider and oscillator with three
oscillator terminals
, ten buffered outputs and an overriding asynchronous master reset input. The
oscillator configuration allows design of either RC or crystal oscillator circuits. The oscillator
may be replaced by an external clock signal at input RS. The counter advances on the
negative-going transition of RS.
A HIGH level on MR resets the counter (O3 to O9 and O11 to O13 =
LOW), independent of other input conditions.
Schmitt-trigger action in the clock input makes the
circuit highly tolerant to slower clock rise and fall times.
7.2.51 4066 (Quad Analog Switches)
The 4066 device has four independent bilateral analogue switches (transmission gates). Each
switch has two input/output terminals (Y/Z) and an active HIGH enable input (E).
When the C input is high, the input/outputs A and B, will pass either digital or analog signals
in either direction.
