SN74LV163APWR

Texas Instruments · Counters, Dividers · TSSOP-16

SN74LV163APWR from Texas Instruments, in a TSSOP-16. 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 CLR input Clear input, active low, resets all counter outputs
2 CLK input Clock input, rising edge triggered for synchronous counting
3 A input Parallel load data input A
4 B input Parallel load data input B
5 C input Parallel load data input C
6 D input Parallel load data input D
7 ENP input Count enable input that does not affect the ripple-carry output
8 GND power_in Ground, 0V reference
9 LOAD input Parallel load control input, active low
10 ENT input Count enable input that affects the ripple-carry output
11 QD output Counter output bit D
12 QC output Counter output bit C
13 QB output Counter output bit B
14 QA output Counter output bit A
15 RCO output Ripple-carry output for cascading counters
16 VCC power_in Supply voltage with operating range 2V to 5.5V
