!
The MC14597B and MC14598B are 8–bit latches, one addressed with an
internal counter and the other addressed with an external binary address.
The 8 latch–outputs are high drive, three–state and bus line compatible. The
drive capability allows direct applications with MPU systems such as the
Motorola 6800 family.
With MC14597B, a 3–bit address counter (clocked on the falling edge of
Increment) selects the appropriate latch. The latches of the MC14598B are
accessed via the Address pins, A0, A1, and A2. A Full Flag is provided on
the MC14597B to indicate the position of the Address counter.
All 8 outputs from the latches are available in parallel when Enable is in the
low state. Data is entered into a selected latch from the Data pin when the
Strobe is high. Master reset is available on both parts.
