Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OE1 | input | Active-low output enable 1; when either OE1 or OE2 is high the Y outputs go to high-impedance (three-state); both OE1 and OE2 must be low for the buffered data to appear on the outputs. |
| 2 | A0 | input | Buffered data input 0 to the octal noninverting buffer/line driver. |
| 3 | A1 | input | Buffered data input 1 to the octal noninverting buffer/line driver. |
| 4 | A2 | input | Buffered data input 2 to the octal noninverting buffer/line driver. |
| 5 | A3 | input | Buffered data input 3 to the octal noninverting buffer/line driver. |
| 6 | A4 | input | Buffered data input 4 to the octal noninverting buffer/line driver. |
| 7 | A5 | input | Buffered data input 5 to the octal noninverting buffer/line driver. |
| 8 | A6 | input | Buffered data input 6 to the octal noninverting buffer/line driver. |
| 9 | A7 | input | Buffered data input 7 to the octal noninverting buffer/line driver. |
| 10 | GND | power_in | Ground (0 V) supply reference pin. |
| 11 | Y7 | tri_state | Three-state noninverting buffered output 7, corresponding to A7; capable of driving 15 LSTTL loads; high impedance when OE1 or OE2 is high. |
| 12 | Y6 | tri_state | Three-state noninverting buffered output 6, corresponding to A6; capable of driving 15 LSTTL loads; high impedance when OE1 or OE2 is high. |
| 13 | Y5 | tri_state | Three-state noninverting buffered output 5, corresponding to A5; capable of driving 15 LSTTL loads; high impedance when OE1 or OE2 is high. |
| 14 | Y4 | tri_state | Three-state noninverting buffered output 4, corresponding to A4; capable of driving 15 LSTTL loads; high impedance when OE1 or OE2 is high. |
| 15 | Y3 | tri_state | Three-state noninverting buffered output 3, corresponding to A3; capable of driving 15 LSTTL loads; high impedance when OE1 or OE2 is high. |
| 16 | Y2 | tri_state | Three-state noninverting buffered output 2, corresponding to A2; capable of driving 15 LSTTL loads; high impedance when OE1 or OE2 is high. |
| 17 | Y1 | tri_state | Three-state noninverting buffered output 1, corresponding to A1; capable of driving 15 LSTTL loads; high impedance when OE1 or OE2 is high. |
| 18 | Y0 | tri_state | Three-state noninverting buffered output 0, corresponding to A0; capable of driving 15 LSTTL loads; high impedance when OE1 or OE2 is high. |
| 19 | OE2 | input | Active-low output enable 2; when either OE1 or OE2 is high the Y outputs go to high-impedance (three-state); both OE1 and OE2 must be low for the buffered data to appear on the outputs. |
| 20 | VCC | power_in | Positive supply voltage; for the HCT types the recommended operating range is 4.5 V to 5.5 V. |
