78P7200
E3/DS3/STS-1
Line Interface Unit
ELECTRICAL SPECIFICATIONS
(TA = -40°C to 85°C, Vcc = 5V ±5%, unless otherwise noted.) Currents flowing into the chip are positive. Current
maximums are currents with the largest absolute value. Operation above absolute maximum ratings may
permanently damage the device.
