TC74HC148AF 8-to-3 Line Priority Encoder

TC74HC148AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC148AP, TC74HC148AF 8-to-3 Line Priority Encoder The TC74HC148A is a high speed CMOS 8-to-3 LINE ENCODER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. All data inputs and outputs of these encoders are active at the low logic level. The encoder detects a low level of the highest order among eight input s.

TC74HC148AF Features
