Product Summary

The C70021D is an quadruple NOR gate. The C70021D performs the Boolean function Y = A·B or Y = A + B in positive logic. However, because of the Schmitt action, the inputs have different input threshold levels for positive- and negative-going signals.

Parametrics

C70021D absolute maximum ratings: (1)Supply voltage range, VCC: –0.5 V to 7 V ; (2)Input clamp current, IIK (VI < 0 or VI > VCC): ±20 mA ; (3)Output clamp current, IOK (VO < 0 or VO > VCC): ±20 mA; (4)Continuous output current, IO (VO = 0 to VCC): ±25 mA; (5)Continuous current through VCC or GND: ±50 mA ; (6)Package thermal impedance, θJA: 86℃/W; (7)Storage temperature range, Tstg: –65 to 150℃.

Features

C70021D features: (1)Wide Operating Voltage Range of 2 V to 6 V; (2)Typical tpd = 14 ns; (3)Low Power Consumption, 20-μA Max ICC; (4)Low Input Current of 1 μA Max; (5)Operation From Very Slow Input Transitions; (6)Temperature-Compensated Threshold Levels; (7)High Noise Immunity.
