Texas Instruments · Shift Registers · SOIC-14
SN74ALS164ADR from Texas Instruments, in a SOIC-14. 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 | A | input | AND-gated serial data input: a low at A inhibits entry of new data and resets the first flip-flop to low at the next clock pulse, and A determines the first flip-flop state only while B is high. |
| 2 | B | input | AND-gated serial data input: a low at B inhibits entry of new data and resets the first flip-flop to low at the next clock pulse, and B determines the first flip-flop state only while A is high. |
| 3 | QA | output | Parallel output of the first register stage, which takes the AND of the serial inputs on each low-to-high CLK transition and is forced low by CLR. |
| 4 | QB | output | Parallel output of register stage B, which shifts in the previous QA level on each low-to-high CLK transition and is forced low by CLR. |
| 5 | QC | output | Parallel output of register stage C, which shifts in the previous QB level on each low-to-high CLK transition and is forced low by CLR. |
| 6 | QD | output | Parallel output of register stage D, which shifts in the previous QC level on each low-to-high CLK transition and is forced low by CLR. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | CLK | input | Clock input; data shifts on the low-to-high-level transition of CLK and the clock input is fully buffered. |
| 9 | CLR | input | Direct asynchronous clear: a low level sets all outputs QA through QH to low regardless of the clock. |
| 10 | QE | output | Parallel output of register stage E, which shifts in the previous QD level on each low-to-high CLK transition and is forced low by CLR. |
| 11 | QF | output | Parallel output of register stage F, which shifts in the previous QE level on each low-to-high CLK transition and is forced low by CLR. |
| 12 | QG | output | Parallel output of register stage G, which shifts in the previous QF level on each low-to-high CLK transition and is forced low by CLR. |
| 13 | QH | output | Parallel output of the last register stage H, which shifts in the previous QG level on each low-to-high CLK transition and is forced low by CLR. |
| 14 | VCC | power_in | Supply voltage: recommended 4.5 V to 5.5 V (5 V nominal), with an absolute maximum of 7 V. |
