SN74HC259PWR from Texas Instruments, 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 | S0 | input | Address select input 0 (LSB); with S1 and S2 selects which of the eight latches (0-7) is addressed per the Latch Selection Table. |
| 2 | S1 | input | Address select input 1; with S0 and S2 selects which of the eight latches (0-7) is addressed per the Latch Selection Table. |
| 3 | S2 | input | Address select input 2 (MSB); with S0 and S1 selects which of the eight latches (0-7) is addressed per the Latch Selection Table. |
| 4 | Q0 | output | Latch output 0; in addressable-latch or demultiplex mode follows the D input when addressed, otherwise holds its previous state or is forced low by CLR. |
| 5 | Q1 | output | Latch output 1; in addressable-latch or demultiplex mode follows the D input when addressed, otherwise holds its previous state or is forced low by CLR. |
| 6 | Q2 | output | Latch output 2; in addressable-latch or demultiplex mode follows the D input when addressed, otherwise holds its previous state or is forced low by CLR. |
| 7 | Q3 | output | Latch output 3; in addressable-latch or demultiplex mode follows the D input when addressed, otherwise holds its previous state or is forced low by CLR. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | Q4 | output | Latch output 4; in addressable-latch or demultiplex mode follows the D input when addressed, otherwise holds its previous state or is forced low by CLR. |
| 10 | Q5 | output | Latch output 5; in addressable-latch or demultiplex mode follows the D input when addressed, otherwise holds its previous state or is forced low by CLR. |
| 11 | Q6 | output | Latch output 6; in addressable-latch or demultiplex mode follows the D input when addressed, otherwise holds its previous state or is forced low by CLR. |
| 12 | Q7 | output | Latch output 7; in addressable-latch or demultiplex mode follows the D input when addressed, otherwise holds its previous state or is forced low by CLR. |
| 13 | D | input | Serial/parallel data input written into the addressed latch when G is active (low) and CLR is high (per the Function Table). |
| 14 | G | input | Active-low enable input; when low the addressed latch follows D (addressable-latch mode) or the device operates as a 1-of-8 demultiplexer; when high (inactive) all latches hold their previous state (memory mode) and address lines can change without corrupting data. |
| 15 | CLR | input | Active-low asynchronous parallel clear; when low, all eight outputs are forced low regardless of the address and data inputs (with G high) or configures 1-of-8 demultiplexer mode (with G low). |
| 16 | VCC | power_in | Positive supply voltage, recommended operating range 2 V to 6 V. |
