SN75477P

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · PDIP-8

SN75477P from Texas Instruments, in a PDIP-8. 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 S input Strobe input shared by both NAND drivers; the SN75477 output is Y = NOT(A AND S) per the function table, with VIH minimum 2 V and VIL maximum 0.8 V.
2 1A input Logic input of driver 1 with diode-clamped, TTL- or MOS-compatible pnp input; input current IIL is -80 to -110 µA at VI = 0.8 V, and the input clamp voltage is -1.5 V maximum at II = -12 mA.
3 1Y output High-voltage open-drain-style output of driver 1, characterized for use to 300 mA with output breakdown voltage of 70 V minimum (100 V typical) and continuous output current rated to 400 mA absolute maximum.
4 GND power_in Network ground reference; all datasheet voltage values are referenced to this pin.
5 CLAMP passive Common output clamp diode connection providing inductive transient suppression for both outputs, rated 300 mA and 70 V, with clamp current IOK limited to 400 mA absolute maximum.
6 2Y output High-voltage output of driver 2, characterized for use to 300 mA with output breakdown voltage of 70 V minimum (100 V typical) and continuous output current rated to 400 mA absolute maximum.
7 2A input Logic input of driver 2 with diode-clamped, TTL- or MOS-compatible pnp input; input current IIL is -80 to -110 µA at VI = 0.8 V, and the input clamp voltage is -1.5 V maximum at II = -12 mA.
8 VCC power_in Supply voltage with recommended range 4.5 V to 5.5 V (5 V nominal) and absolute maximum rating of 7 V with respect to network GND.
