74HC192M

HGSEMI · Counters, Dividers · SOP-16

74HC192M from HGSEMI, in a SOP-16. 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 D1 input Data input D1 for parallel load operation; loaded into counter when PL is LOW.
2 Q1 output Flip-flop output Q1; changes state synchronously with clock transitions.
3 Q0 output Flip-flop output Q0; changes state synchronously with clock transitions.
4 CPD input Count down clock input; LOW-to-HIGH edge triggered; device counts down when pulsed while CPU is held HIGH.
5 CPU input Count up clock input; LOW-to-HIGH edge triggered; device counts up when pulsed while CPD is held HIGH.
6 Q2 output Flip-flop output Q2; changes state synchronously with clock transitions.
7 Q3 output Flip-flop output Q3; changes state synchronously with clock transitions.
8 GND power_in Ground connection providing 0 V reference for device operation.
9 D3 input Data input D3 for parallel load operation; loaded into counter when PL is LOW.
10 D2 input Data input D2 for parallel load operation; loaded into counter when PL is LOW.
11 PL input Asynchronous parallel load input (active LOW); loads data from D0-D3 into outputs when LOW.
12 TCU output Terminal count up (carry) output (active LOW); goes LOW when circuit reaches count of 9 and CPU transitions HIGH-to-LOW.
13 TCD output Terminal count down (borrow) output (active LOW); goes LOW when circuit is in zero state and CPD transitions HIGH-to-LOW.
14 MR input Asynchronous master reset input (active HIGH); resets all outputs Q0-Q3 to LOW and disables parallel load gates.
15 D0 input Data input D0 for parallel load operation; loaded into counter when PL is LOW.
16 VCC power_in Positive supply voltage required for device operation.
