74LCX74MTCX

onsemi · Logic ICs · TSSOP-14

74LCX74MTCX from onsemi, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CD1 input Active-low direct clear input of flip-flop 1; a LOW level sets Q1 LOW independent of the clock.
2 D1 input Data input of flip-flop 1, transferred to Q1 on the rising edge of CP1 (5V tolerant, VI max 5.5V).
3 CP1 input Clock pulse input of flip-flop 1, positive edge-triggered.
4 SD1 input Active-low direct set input of flip-flop 1; a LOW level sets Q1 HIGH independent of the clock.
5 Q1 output True output of flip-flop 1 with ±24mA drive at VCC = 3.0V-3.6V.
6 Q1_N output Complementary output of flip-flop 1 with ±24mA drive at VCC = 3.0V-3.6V.
7 GND power_in Ground pin (0V reference).
8 Q2_N output Complementary output of flip-flop 2 with ±24mA drive at VCC = 3.0V-3.6V.
9 Q2 output True output of flip-flop 2 with ±24mA drive at VCC = 3.0V-3.6V.
10 SD2 input Active-low direct set input of flip-flop 2; a LOW level sets Q2 HIGH independent of the clock.
11 CP2 input Clock pulse input of flip-flop 2, positive edge-triggered.
12 D2 input Data input of flip-flop 2, transferred to Q2 on the rising edge of CP2 (5V tolerant, VI max 5.5V).
13 CD2 input Active-low direct clear input of flip-flop 2; a LOW level sets Q2 LOW independent of the clock.
14 VCC power_in Supply voltage, 2.0V to 3.6V operating (2.3V-3.6V specified), absolute maximum -0.5V to +7.0V.
