Product Summary

The LM119J is a precision high speed dual comparator. The device is fabricated on a single monolithic chip. The LM119J is designed to operate over a wide range of supply voltages down to a single 5V logic supply and ground. Furthermore, it has a higher gain and lower input current than other devices. The uncommitted collector of the output stage makes the LM119J compatible with RTL, DTL and TTL as well as capable of driving lamps and relays at currents up to 25mA.

Parametrics

LM119J absolute maximum ratings: (1)Total Supply Voltage: 36V; (2)Output to Negative Supply Voltage: 36V; (3)Ground to Negative Supply Voltage: 25V; (4)Ground to Positive Supply Voltage: 18V; (5)Differential Input Voltage: +5V; (6)Input Voltage: +15V; (7)Power Dissipation: 500mW; (8)Output Short Circuit Duration: 10 seconds; (9)Maximum Junction Temperature: 150℃; (10)Storage Temperature Range: -65 C to 150℃; (11)Lead Temperature (Soldering, 10 seconds): 260℃.

Features

LM119J features: (1)Two independent comparators; (2)Operates from a single 5V supply; (3)Typically 80nS response time at +15V; (4)Minimum fan-out of 2 each side; (5)Maximum input current of 1uA over temperature; (6)Inputs and outputs can be isolated from system ground; (7)High common mode slew rate.
