4-BIT BIDIRECTIONAL COUNTERS
(WITH 3-STATE OUTPUTS)
The MC54/74F568 and MC54/74F569 are fully synchronous, reversible
counters with 3-state outputs. The F568 is a BCD decade counter; the F569
is a binary counter. They feature preset capability for programmable opera-
tion, carry lookahead for easy cascading, and a U/D input to control the direc-
tion of counting. For maximum flexibility there are both synchronous and mas-
ter asynchronous reset inputs as well as both Clocked Carry (CC) and
Terminal Count (TC) outputs. All state changes except Master Reset are initi-
ated by the rising edge of the clock. A HIGH signal on the Output Enable (OE)
input forces the output buffers into the high impedance state but does not pre-
vent counting, resetting or parallel loading.
