Notes
1. The circuit has two clock inputs CLK and CLK. There are four modes of operation:
a) TTL (mode 1); CLK decoupled to DGND by a capacitor. CLK input is TTL threshold voltage of 1.5 V and sampling
on the LOW-to-HIGH transition of the input clock signal.
b) TTL (mode 2); CLK decoupled to DGND by a capacitor. CLK input is TTL threshold voltage of 1.5 V and sampling
on the HIGH-to-LOW transition of the input clock signal.
c) AC drive modes (modes 3 and 4); When driving the CLK input directly and with any AC signal of 0.5 V
(peak-to-peak value) imposed on a DC level of 1.5 V, sampling takes place on the LOW-to-HIGH transition of the
clock signal. When driving the CLK input with such a signal, sampling takes place on the HIGH-to-LOW transition.
d) If one of the clock inputs is not driven, then it is recommended to decouple this input to DGND with a 100 nF
capacitor.
HANDLING
Inputs and outputs are protected against electrostatic discharges in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling integrated circuits.
