SN54HCT374, SN74HCT374 SCLS005E – MARCH 1984 – REVISED FEBRUARY 2022 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. The eight flip-flops of the ’HCT374 devices are edgetriggered D-type flip-flops. On the positive transition ofthe clock (CLK) input, the Q outputs are set to the logic levels that were set up at the data (D) inputs. An output-enable (OE) input places the eight outputs in either a normal logic state (high or low logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without interface or pullup components.
