ITT - Index of

ITr74141
BCD-TO-DECIMAL DECODER/DRIVER
Low-forward-impedance diodes are also provided
for each input to clamp negative-voltage transitions
in order to minimize transmission-line effects. Power
dissipation is typically 55 milliwatts. The ITT-
74141 is characterized for operation over the temperature
range of OOC to 70°C.
