CDx4HC(T)166 High-Speed
CMOS Logic 8-Bit Parallel-In/Serial-Out Shift Register
1 Features
2 Description
Buffered inputs
The ’HC166 and ’HCT166 8-bit shift register is
Fanout (over temperature range)
fabricated with silicon gate
CMOS technology. It
– Standard outputs: 10 LSTTL Loads
– Bus driver outputs: 15 LSTTL Loads
Wide operating temperature range: -55℃ to 125℃ Balanced propagation delay and transition time
possesses the low power consumption of standard
CMOS integrated circuits, and can operate at speeds comparable to the equivalent low power Schottky device.
Significant power reduction compared to LSTTL Logic ICs
HC Types
– 2 V to 6 V operation – High noise immunity: NIL = 30%, NIH = 30% of
VCC at VCC = 5 V HCT Types
