This dual 4-bit D-type edge-triggered flip-flop features 3-state outputs designed specifically for bus driving. This makes these devices particularly suitable for implementing buffer registers, I/O ports, and working registers.

The flip-flops enter data on the low-to-high transition of the clock. The 74AC11874 has clear (1CLR and 2CLR) inputs and noninverting outputs. Taking CLR low causes the four Q outputs to go low independently of the clock.

The 74AC11874 is characterized for operation from 40°C to 85°C.

The 74AC11874 is designed as dual 4-bit D-type edge-triggered flip-flop which features 3-state outputs designed specifically for bus driving. This makes these devices particularly suitable for implementing buffer registers, I/O ports, and working registers.

It has seven features of the 74AC11874. (1)3-state buffer-type outputs drive bus lines directly. (2)Asynchronous clear. (3)Flow-through architecture optimizes PCB layout. (4)Center-pin Vcc and GND configurations minimize high-speed switching noise. (5)EPIC (enhanced-performance implanted CMOS) 1mm process. (6)500mA typical latch-up immunity at 125°C. (7)Package options include plastic small-outline packages and standard plastic 300mil DIPs. Those are all the main features.

Some absolute maximum ratings of the 74AC11874 have been concluded into several points as follow. (1)Its supply voltage range would be from -0.5V to 7V. (2)Its input voltage range would be from -0.5V to Vcc+0.5V. (3)Its output voltage range would be from -0.5V to Vcc+0.5V. (4)Its input clamp current would be +/-20mA. (5)Its output clamp current would be +/-50mA. (6)Its continuous output current would be +/-50mA. (7)Its continuous current through Vcc or GND pins would be +/-200mA. (8)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of the 74AC11874 are concluded as follow. (1)Its Voh would be min 2.9V. (2)Its Vol would be max 0.1V. (3)Its Ii would be max +/-0.1uA. (4)Its Ioz would be max +/-0.5uA. (5)Its Icc would be max 8uA. (6)Its Ci would be typ 4.5pF. (7)Its Co would be typ 13.5pF. (8)Its clock frequency would be min 0MHz and max 60MHz. (9)Its pulse duration would be min 4ns for CLR low and would be min 8.3ns for CLK high or low. (10)Its setup time before CLK would be min 3ns for data and would be min 1.5ns for CLR inactive.
