INPUT/OUTPUT DESCRIPTION:

SENSE (Pin 1)

A logic 0 applied to this input for a minimum of three SYNC cy-

cles, TS1 (50ms for 60Hz, 60ms for 50Hz), causes the circuit to

step to the next state in the operating sequence.

SLAVE (Pin 2)

Same description as SENSE (Pin 1) except that logic 1 replaces

logic 0. This input is designed to be used with Remote Exten-

sions (See Figure 5 and Figure 6.)

Supply voltage negative terminal.

TRIG (Pin 4)

TRIG is a negative-going pulse occurring once every half cycle

of the SYNC input. Pulse width is 33µs. Table 1 in the General

Description shows values of the TRIG phase angle for the differ-

ent states. (See Figure 2 and Figure 3.)

Supply voltage positive terminal.

OSC (Pin 6)

An R-C network connected to this input controls the frequency of

approximately 255RC. The Oscillator is active only in State 1. Chip

to chip Oscillation Tolerance is ±10% for fixed value of RC. Tie Pin

CAP (Pin 7)

The CAP input is for external component connection for the PLL fil-

ter capacitor. (See Figure 5.)

SYNC (Pin 8)

The AC Line Frequency (50/60Hz) is applied to this input. The

Phase-Lock Loop synchronizes all internal timings to the AC signal

at the SYNC input. (See Figure 5.)
