SNx4HCT273 Octal D-Type Flip-Flops With Clear
1 Features
• Operating voltage range of 4.5V to 5.5V • Outputs can drive up to 10 LSTTL loads • Low power consumption, 80µA maximum ICC • Typical tpd = 12ns • ±4mA output drive at 5V • Low input current of 1µA maximum • Inputs are TTL-voltage compatible • Contain eight D-type flip-flops • Direct clear input
2 Applications
• Buffer or storage registers • Shift registers • Pattern generators
3 Description
These devices are positive-edge-triggered D-type flipflops with a 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.
