MC1458P from Texas Instruments, in a PDIP-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	1OUT	output	Output of amplifier 1. Short-circuit protected; can drive loads down to 2 kOhm with typical +/-13 V swing at VCC = +/-15 V. Output resistance ~75 Ohm; short-circuit output current typ +/-25 mA.
2	1IN-	input	Inverting input of amplifier 1. High-impedance input (typ 2 MOhm); input bias current typ 80 nA, input offset current typ 20 nA. Must not exceed
3	1IN+	input	Non-inverting input of amplifier 1. Common-mode input voltage range typ +/-13 V at VCC = +/-15 V. Differential input voltage rating +/-30 V absolute max.
4	VCC-	power_in	Negative supply rail. Absolute max -18 V for MC1458; recommended operating -5 V to -15 V. Shared by both amplifiers.
5	2IN+	input	Non-inverting input of amplifier 2. Common-mode input voltage range typ +/-13 V at VCC = +/-15 V. Differential input voltage rating +/-30 V absolute max.
6	2IN-	input	Inverting input of amplifier 2. High-impedance input (typ 2 MOhm); input bias current typ 80 nA, input offset current typ 20 nA. Must not exceed
7	2OUT	output	Output of amplifier 2. Short-circuit protected; can drive loads down to 2 kOhm with typical +/-13 V swing at VCC = +/-15 V. Output resistance ~75 Ohm; short-circuit output current typ +/-25 mA.
8	VCC+	power_in	Positive supply rail. Absolute max +18 V for MC1458; recommended operating +5 V to +15 V. Supply current typ 3.4 mA (both amplifiers) at VO = 0, no load.
