NTE4077B and NTE4077BT
Integrated Circuit
CMOS, Quad Exclusive NOR Gate
Description:
The NTE4077B (14−Lead DIP) and NTE4077BT (SOIC−14) are quad exclusive NOR gates
constructed with MOS P−channel and N−channel enhancement mode devices in a single monolithic
structure. These complementary MOS logic gates find primary use where low power dissipation and/
or high noise immunity is desired.
Features:
D Quiescent Current = 0.5nA Typ/Pkg at 5 Vdc
D Noise Immunity = 45% of VDD (Typ)
D Supply Voltage Range = 3Vdc to 18Vdc
D All Outputs Buffered
D Capable of Driving Two Low−Power TTL Loads, One Low−Power Schottky TTL Load or Two
HTL Loads Over the Rated Temperature Range
D Double Diode Protection on All Inputs

Note 1. These devices contain circuitry to protect the inputs against damage due to high static
voltages or electric fields; however, it is advised that normal precautions be taken to avoid
application of any voltage higher than maximum rated voltages to this high impedance cir-
cuit. For proper operation is is recommended that Vin and Vout be constrained to the range
VSS ≤ (Vin or Vout) ≤ VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or
VDD).
