74HCT74PW-Q100

Nexperia · Flip Flops · TSSOP-14

74HCT74PW-Q100 from Nexperia, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1RD input Flip-flop 1 asynchronous reset-direct input, active LOW. Drives 1Q LOW / 1Q_bar HIGH independent of clock. TTL input threshold; VIL max 0.8 V, VIH min 2.0 V at VCC = 4.5 V to 5.5 V.
2 1D input Flip-flop 1 data input. Sampled on the LOW-to-HIGH edge of 1CP and transferred to 1Q. TTL input levels (VIL max 0.8 V, VIH min 2.0 V).
3 1CP input Flip-flop 1 clock input, positive edge-triggered (LOW-to-HIGH). Schmitt-trigger action tolerates slow rise/fall times. TTL input levels.
4 1SD input Flip-flop 1 asynchronous set-direct input, active LOW. Drives 1Q HIGH / 1Q_bar LOW independent of clock. TTL input levels.
5 1Q output Flip-flop 1 true output. CMOS push-pull output; VOH min 3.7 V at IO = -4 mA, VOL max 0.4 V at IO = 4 mA (VCC = 4.5 V, -40 °C to +125 °C). Symmetrical output impedance.
6 1Q_bar output Flip-flop 1 complement output (inverted 1Q). Same drive characteristics as 1Q: VOH min 3.7 V at IO = -4 mA, VOL max 0.4 V at IO = 4 mA (VCC = 4.5 V).
7 GND power_in Ground reference, 0 V. Maximum sink current 100 mA (IGND limiting value).
8 2Q_bar output Flip-flop 2 complement output (inverted 2Q). CMOS push-pull; VOH min 3.7 V at IO = -4 mA, VOL max 0.4 V at IO = 4 mA (VCC = 4.5 V).
9 2Q output Flip-flop 2 true output. CMOS push-pull; VOH min 3.7 V at IO = -4 mA, VOL max 0.4 V at IO = 4 mA (VCC = 4.5 V). Symmetrical output impedance.
10 2SD input Flip-flop 2 asynchronous set-direct input, active LOW. Drives 2Q HIGH / 2Q_bar LOW independent of clock. TTL input levels.
11 2CP input Flip-flop 2 clock input, positive edge-triggered (LOW-to-HIGH). Schmitt-trigger action tolerates slow rise/fall times. TTL input levels.
12 2D input Flip-flop 2 data input. Sampled on the LOW-to-HIGH edge of 2CP and transferred to 2Q. TTL input levels.
13 2RD input Flip-flop 2 asynchronous reset-direct input, active LOW. Drives 2Q LOW / 2Q_bar HIGH independent of clock. TTL input levels.
14 VCC power_in Supply voltage. Recommended 4.5 V to 5.5 V for 74HCT74-Q100; absolute maximum -0.5 V to +7 V. ICC max 80 μA at VCC = 5.5 V, TA up to +125 °C.
