Nexperia · Counters, Dividers · TSSOP-16

74LVC163PW from Nexperia, 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 MR input Synchronous master reset, active LOW; a LOW level sets Q0 to Q3 to LOW after the next positive clock transition, regardless of PE, CET and CEP.
2 CP input Clock input, edge-triggered on the LOW-to-HIGH transition, with all flip-flops clocked simultaneously on this edge.
3 D0 input Parallel data input D0, loaded into the counter on the positive clock edge when PE is LOW.
4 D1 input Parallel data input D1, loaded into the counter on the positive clock edge when PE is LOW.
5 D2 input Parallel data input D2, loaded into the counter on the positive clock edge when PE is LOW.
6 D3 input Parallel data input D3, loaded into the counter on the positive clock edge when PE is LOW.
7 CEP input Count enable input; both CEP and CET must be HIGH for the counter to count.
8 GND power_in Ground (0 V) reference for all voltages in the device.
9 PE input Parallel enable input, active LOW; a LOW level disables counting and loads D0 to D3 on the positive clock edge, subject to PE set-up and hold times.
10 CET input Count enable carry input; it is fed forward to enable the terminal count output TC and must be HIGH for counting.
11 Q3 output Flip-flop output Q3 (most significant bit), which can be preset HIGH or LOW.
12 Q2 output Flip-flop output Q2, which can be preset HIGH or LOW.
13 Q1 output Flip-flop output Q1, which can be preset HIGH or LOW.
14 Q0 output Flip-flop output Q0 (least significant bit), which can be preset HIGH or LOW.
15 TC output Terminal count output, HIGH when CET is HIGH and the counter is at terminal count (HHHH).
16 VCC power_in Supply voltage; recommended operating range is 1.65 V to 3.6 V, with functional operation down to 1.2 V.
