SN75176BP from Texas Instruments, in a DIP-8. 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	R	output	Receiver output. Drives logic-level output derived from the differential inputs A-B. VOH ≥ 2.7 V at IOH = -400 µA; VOL ≤ 0.45 V at IOL = 8 mA. High-impedance (3-state) when RE is high.
2	RE	input	Receiver output enable, active LOW. When RE = L the receiver output R is enabled; when RE = H the receiver output is in the high-impedance state. VIH ≥ 2 V, VIL ≤ 0.8 V.
3	DE	input	Driver output enable, active HIGH. When DE = H the driver outputs A and B are enabled and driven per the D input; when DE = L both A and B are in the high-impedance state. VIH ≥ 2 V, VIL ≤ 0.8 V.
4	D	input	Driver logic-level data input. Controls the state of the differential bus outputs A/B when the driver is enabled (DE = H): D = H drives A high and B low; D = L drives A low and B high.
5	GND	power_in	Ground / network ground reference for all supply and signal voltages.
6	A	bidirectional	Non-inverting differential bus I/O (A terminal). Driver output when DE = H, receiver non-inverting input when RE = L. Wide common-mode range of -7 V to +12 V; driver capable of ±60 mA into a 54-Ω load. Combined driver output / receiver input on the bus.
7	B	bidirectional	Inverting differential bus I/O (B terminal). Driver output when DE = H, receiver inverting input when RE = L. Wide common-mode range of -7 V to +12 V; driver capable of ±60 mA into a 54-Ω load.
8	VCC	power_in	Positive supply input. Single 5-V supply (4.75 V to 5.25 V recommended, 7 V absolute maximum). Typical ICC = 42 mA (outputs enabled), 26 mA (outputs disabled).
