Product details

What this quad op-amp is and where it fits

The TLC27M4CN is a quad general-purpose operational amplifier built on the LinCMOS™ process. It packs four independent amplifiers into a single 14-pin DIP package (14-PDIP) with through-hole mounting.

Temperature grade and deployment boundary

The operating temperature range is 0°C to 70°C — commercial grade only.

Through-hole package — what it means for your BOM

The 14-DIP (0.300", 7.62 mm) package is through-hole only. No surface-mount variant of this exact order code exists.

Frequently asked questions

Is the TLC27M4CN obsolete?

No. The TLC27M4CN is listed as Active with no end-of-life notice. Texas Instruments continues to manufacture it, and it is available through independent distribution.

What is the TLC27M4CN pinout?

The TLC27M4CN uses the standard quad op-amp pinout for a 14-pin DIP: output 1 (pin 1), inverting input 1 (pin 2), non-inverting input 1 (pin 3), V+ (pin 4), non-inverting input 2 (pin 5), inverting input 2 (pin 6), output 2 (pin 7), output 3 (pin 8), inverting input 3 (pin 9), non-inverting input 3 (pin 10), V- (pin 11), non-inverting input 4 (pin 12), inverting input 4 (pin 13), output 4 (pin 14). This matches the pinout of the LM324 and TL084 families.

Can the TLC27M4CN replace an LM324?

Pin-compatible yes, but the electrical differences matter. The TLC27M4CN has a CMOS input stage with 0.7 pA input bias current versus the LM324's bipolar input at roughly 100 nA. That makes the TLC27M4CN a better choice for high-impedance sources, but the 525 kHz gain-bandwidth is lower than the LM324's 1.2 MHz typical. The supply current is also lower at 570 µA for all four channels versus roughly 1.4 mA for the LM324. If the original LM324 circuit depends on the higher bandwidth or the bipolar input characteristics, the swap may not work without adjustment.
