onsemi · Signal Switches, Multiplexers, Decoders · TSSOP-16

74LCX157MTCX from onsemi, in a TSSOP-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 S input Select input. Chooses source 0 (I0x) when LOW and source 1 (I1x) when HIGH. 5 V tolerant CMOS input.
2 I0a input Source 0 data input for multiplexer channel A. Routed to output Za when Select (S) is LOW and Enable (E-bar) is LOW. 5 V tolerant.
3 I1a input Source 1 data input for multiplexer channel A. Routed to output Za when Select (S) is HIGH and Enable (E-bar) is LOW. 5 V tolerant.
4 Za output Multiplexer channel A output (non-inverting). Presents selected I0a or I1a data. Drives ±24 mA at VCC = 3.0 V; forced LOW when Enable (E-bar) is HIGH.
5 I0b input Source 0 data input for multiplexer channel B. Routed to output Zb when Select (S) is LOW and Enable (E-bar) is LOW. 5 V tolerant.
6 I1b input Source 1 data input for multiplexer channel B. Routed to output Zb when Select (S) is HIGH and Enable (E-bar) is LOW. 5 V tolerant.
7 Zb output Multiplexer channel B output (non-inverting). Presents selected I0b or I1b data. Drives ±24 mA at VCC = 3.0 V; forced LOW when Enable (E-bar) is HIGH.
8 GND power_in Ground reference (0 V). Absolute maximum ground current per pin is ±100 mA.
9 Zd output Multiplexer channel D output (non-inverting). Presents selected I0d or I1d data. Drives ±24 mA at VCC = 3.0 V; forced LOW when Enable (E-bar) is HIGH.
10 I1d input Source 1 data input for multiplexer channel D. Routed to output Zd when Select (S) is HIGH and Enable (E-bar) is LOW. 5 V tolerant.
11 I0d input Source 0 data input for multiplexer channel D. Routed to output Zd when Select (S) is LOW and Enable (E-bar) is LOW. 5 V tolerant.
12 Zc output Multiplexer channel C output (non-inverting). Presents selected I0c or I1c data. Drives ±24 mA at VCC = 3.0 V; forced LOW when Enable (E-bar) is HIGH.
13 I1c input Source 1 data input for multiplexer channel C. Routed to output Zc when Select (S) is HIGH and Enable (E-bar) is LOW. 5 V tolerant.
14 I0c input Source 0 data input for multiplexer channel C. Routed to output Zc when Select (S) is LOW and Enable (E-bar) is LOW. 5 V tolerant.
15 ~E input Enable input, active-LOW. When LOW the multiplexer passes the selected source to the Z outputs; when HIGH all Z outputs are forced LOW regardless of other inputs. 5 V tolerant.
16 VCC power_in Positive supply voltage. Operating range 2.3 V to 3.6 V (recommended 2.0-3.6 V). Absolute maximum -0.5 V to +7.0 V; DC supply current per pin limited to ±100 mA.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: onsemi datasheet (None pp, sha256 1106038f6625032a, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
