The HC273 and HCT273 high-speed octal D-type flip-flops feature a direct clear input and are fabricated using silicon gate CMOS technology. They offer the low power consumption characteristics of standard CMOS ICs. Data at the D inputs is transferred to the Q outputs on the rising edge of the clock pulse. All eight flip-flops are controlled by a common clock (CLK) and a common reset (CLR). Reset is accomplished by a low voltage level, independent of the clock. All eight Q outputs can be reset to logic 0.

• General clock and asynchronous controller reset
• Positive-edge triggered
• Buffered inputs
• Fan-out (over temperature range)
  • Standard outputs: 10 LSTTL loads
  • Bus driver outputs: 15 LSTTL loads
• Wide operating temperature range: -55℃ to 125℃
• Balanced propagation delays and transition times
• Significantly reduced power consumption compared to LSTTL logic ICs
• HC type:
  • Operating voltage: 2V to 6V
  • High noise immunity: NIL = 30%, NIH = 30% of VCC when VCC = 5V
• HCT type:
  • Operating voltage: 4.5V to 5.5V
  • Direct LSTTL input logic compatibility, VIL = 0.8V (max), VIH = 2V (min)
  • CMOS input compatibility at VOL, VOH voltages, II ≤ 1 μA
