Texas Instruments CD54HC374F3A
The ’HC374, ’HCT374, ’HC574, and ’HCT574 are octal D-type flip-flops with 3-state outputs and the capability to drive 15 LSTTL loads. The eight edgetriggered flip-flops enter data into their registers on the LOW to HIGH transition of clock (CP).| Part No. | CD54HC374F3A |

FEATURES
● Buffered inputs● Common three-state output enable control
● Three-state outputs
● Bus line driving capability
● Typical propagation delay (clock to Q) = 15 ns at VCC = 5 V, CL = 15 pF, TA = 25℃
● Fanout (over temperature range) – Standard outputs: 10 LSTTL loads – Bus driver outputs: 15 LSTTL loads
● Wide operating temperature range: –55℃ to 125℃
● Balanced propagation delay and transition times
● Significant power reduction compared to LSTTL Logic ICs
● HC types – 2-V to 6-V operation – High noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5 V
● HCT types – 4.5-V to 5.5-V Operation – Direct LSTTL input logic compatibility, VIL = 0.8 V (max), VIH = 2 V (min) – CMOS input compatibility, II ≤ 1μA at VOL, VOH 2
DESCRIPTION
The output enable (OE) controls the 3-state outputs and is independent of the register operation. When OE is HIGH, the outputs are in the high-impedance state. The 374 and 574 are identical in function and differ only in their pinout arrangements. PART N...
