CD4572UBM

Texas Instruments · Logic Gates · SOIC-16

CD4572UBM from Texas Instruments, in a SOIC-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 J output Output J = inverse of A, from inverter 1 (one of four identical inverters).
2 A input Input A of inverter 1; protected by CMOS protection network, input range -0.5 V to VDD+0.5 V.
3 K output Output K = inverse of B, from inverter 2.
4 B input Input B of inverter 2; input range -0.5 V to VDD+0.5 V.
5 L output Output L = NOT(C+D), output of the 2-input NOR gate.
6 C input NOR gate input C; input range -0.5 V to VDD+0.5 V.
7 D input NOR gate input D, positioned adjacent to VSS for easy use of the gate as an inverter.
8 VSS power_in Ground / negative supply terminal; all voltages are referenced to VSS.
9 M output Output M = inverse of E, from inverter 3.
10 E input Input E of inverter 3; input range -0.5 V to VDD+0.5 V.
11 N output Output N = inverse of F, from inverter 4.
12 F input Input F of inverter 4; input range -0.5 V to VDD+0.5 V.
13 P output Output P = NOT(G·H), output of the 2-input NAND gate.
14 G input NAND gate input G; input range -0.5 V to VDD+0.5 V.
15 H input NAND gate input H, positioned adjacent to VDD for easy use of the gate as an inverter.
16 VDD power_in Positive supply; recommended range 3 V to 18 V, absolute maximum -0.5 V to +20 V relative to VSS.
