NC7SV74

TinyLogic ULP-A D-Type Flip-Flop

with Preset and Clear

General Description

Features

■ Space saving US8 surface mount package

The NC7SV74 is a single D-type CMOS Flip-Flop with pre-

set and clear from Fairchild’s Ultra Low Power-A (ULP-A)

Series of TinyLogic in both the space saving US8 and

MicroPak packages. ULP-A is ideal for applications that

require extreme high speed, high drive and low power. This

product is designed for a wide low voltage operating range

(0.9V to 3.6V V_CC) and applications that require more drive

■ MicroPak leadless package

■ 0.9V to 3.6V V_CCsupply operation

■ 3.6V overvoltage tolerant I/Os at V_CCfrom 0.9V to 3.6V

■ Extremely High Speed t_PD

1.0 ns typ for 2.7V to 3.6V V_CC

and speed than the TinyLogic ULP series, but still require

low power consumption.

1.2 ns typ for 2.3V to 2.7V V_CC

The NC7SV74 is uniquely designed for optimized power

and speed, and is fabricated with an advanced CMOS

technology to achieve high-speed operation while main-

taining low CMOS power dissipation.

1.9 ns typ for 1.65V to 1.95V V_CC

3.2 ns typ for 1.4V to 1.6V V_CC

6.0 ns typ for 1.1V to 1.3V V_CC

13.0 ns typ for 0.9V V_CC

The signal level applied to the D input is transferred to the

Q output during the positive going transition of the CLK

pulse.

■ Power-Off high impedance inputs and outputs

■ High Static Drive (I_OH/I_OL

)

Battery Life vs. V Supply Voltage

TinyLogic ULP and ULP-A with up to 50% less power consumption can

extend your battery life significantly.

Battery Life = (V_battery*I_battery*.9)/(P_device)/24hrs/day

Where, P_device= (I_CC* V_CC) + (C_PD+ C_L) * V_CC²* f

Assumes ideal 3.6V Lithium Ion battery with current rating of 900mAH and

derated 90% and device frequency at 10MHz, with C_L= 15 pF load

safety of the device cannot be guaranteed. The device should not be oper-

ated at these limits. The parametric values defined in the Electrical Charac-
