SN74HCT273N

The SN74HCT273N is an octal positive-edge-triggered D-type Flip-flop with clear and common enable input. The HCT273 devices are similar to the HCT377 devices, but feature a common clear enable (CLR\) input instead of a latched clock. Information at the data (D) inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not directly related to the positive-going pulse. When CLK is at either the high or low level, the D input has no effect at the output. The circuits are designed to prevent false clocking by transitions at (CLR\).

• Inputs are TTL-voltage compatible
• Typical tpd = 12ns
• 80µA Maximum low power consumption
• ±4mA Output drive at 5V
• 1µA Maximum low input current
