74ABT74 Dual D-type flip-flop with set and reset positive edge-trigger Rev. 3 12 October 2020 Product data sheet 1. General description The 74ABT74 is a dual positive edge triggered D-type flip-flop with individual data (D), clock (CP), set (SD) and reset (RD) inputs, and complementary Q and Q outputs. Data at the D-input that meets the set-up and hold time requirements on the LOW-to-HIGH clock transition will be stored in the flip-flop and appear at the Q output. This device is fully specified for partial power down applications using I . The I circuitry disables the output, preventing the potentially damaging OFF OFF backflow current through the device when it is powered down. 2. Features and benefits Supply voltage range from 4.5 V to 5.5 V BiCMOS high speed and output drive Direct interface with TTL levels Power-up 3-state I circuitry provides partial Power-down mode operation OFF Latch-up protection exceeds 500 mA per JESD78B class II level A ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V Specified from -40 C to +85 C 3.
