CD4044BDR

Texas Instruments · Latches · SOIC-16

CD4044BDR from Texas Instruments, in a SOIC-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 Q4 tri_state Latch 4 3-state output. Driven by latch 4 state when ENABLE=1; high-impedance when ENABLE=0.
2 NC unconnected No connection.
3 S1 input SET input for latch 1. Active-high; sets Q1 when asserted (subject to NAND latch truth table).
4 R1 input RESET input for latch 1. Active-high; resets Q1 when asserted (subject to NAND latch truth table).
5 R2 input RESET input for latch 2.
6 S2 input SET input for latch 2.
7 Q2 tri_state Latch 2 3-state output. Driven by latch 2 state when ENABLE=1; high-impedance when ENABLE=0.
8 VSS power_in Negative supply / ground reference (0 V).
9 ENABLE input Common 3-state ENABLE input for all four latch outputs. Logic '1' connects internal latch states to Q1-Q4; logic '0' places all Q outputs in high-impedance for common-bus operation.
10 Q3 tri_state Latch 3 3-state output. Driven by latch 3 state when ENABLE=1; high-impedance when ENABLE=0.
11 S3 input SET input for latch 3.
12 R3 input RESET input for latch 3.
13 Q1 tri_state Latch 1 3-state output. Driven by latch 1 state when ENABLE=1; high-impedance when ENABLE=0.
14 R4 input RESET input for latch 4.
15 S4 input SET input for latch 4.
16 VDD power_in Positive supply. Recommended operating range 3-18 V (absolute max −0.5 to +20 V referenced to VSS).
