Preliminary Information

† Exceeding these values may cause permanent damage. Functional operation under these conditions is not implied.

‡ Typical figures are at 25

°C with nominal+ 5V supplies and are for design aid only: not guaranteed and not subject to production testing.

y SHK output consists of a 100k

Ω resistor in series with an op-amp with a minimum output voltage swing of ±3.25V.

z LED outputs consists of a 2.5k

Ω resistor in series with SHK op-amp output.

RRC input consists of a 5kW resistor in series with the base lead of the relay driver transistor (grounded emitter).

{ The MUTE input is internally pulled up. With no input connection, the voltage level at the MUTE input is typically at 1.5V.
