SN74HC193QPWRG4Q1

Texas Instruments · Counters, Dividers · TSSOP-16

SN74HC193QPWRG4Q1 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 B input Data input B for parallel load when LOAD is low.
2 QB output Flip-flop output B.
3 QA output Flip-flop output A.
4 DOWN input Count down clock input (active on rising edge when UP is high).
5 UP input Count up clock input (active on rising edge when DOWN is high).
6 QC output Flip-flop output C.
7 QD output Flip-flop output D.
8 GND power_in Ground (0 V reference).
9 D input Data input D for parallel load when LOAD is low.
10 C input Data input C for parallel load when LOAD is low.
11 LOAD input Parallel load control input (active low); loads data inputs A-D into flip-flops when low.
12 CO output Carry output; produces active low pulse when count reaches 15 and UP is low.
13 BO output Borrow output; produces active low pulse when count reaches 0 and DOWN is low.
14 CLR input Clear input (active high); forces all outputs to low level when high.
15 A input Data input A for parallel load when LOAD is low.
16 VCC power_in Supply voltage; operating range 2 V to 6 V.
