SNx4HCT374 Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs
1 Features
• Operating voltage range of 4.5 V to 5.5 V • High-current 3-state true outputs can drive up to
15 LSTTL loads • Low power consumption, 80-μA max ICC • Typical tpd = 22 ns • ±6-mA output drive at 5 V • Low input current of 1 μA max • Inputs are TTL-voltage compatible • Eight D-type flip-flops in a single package • Full parallel access for loading
2 Description
These 8-bit flip-flops feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
