It delivers a gain-bandwidth product of 210 kHz and a slew rate of 0.12 V/µs — enough for slow sensor conditioning, battery monitoring, and multi-channel analog front-ends where power is tight.
Housed in a 14-lead PDIP (0.300-inch body width, 7.62 mm pitch), this is a through-hole part.
The difference is the package: TLC2254AIN is the 14-pin PDIP (through-hole) version, while TLC2254AID is the SOIC-14 (surface-mount) version. Electrical specs are identical.
Yes, in many circuits. The TLC2254AIN is a CMOS rail-to-rail output op-amp with much lower supply current (160 µA vs ~1 mA for LM324) and lower input bias current (1 pA vs ~100 nA). However, its 210 kHz GBW is lower than the LM324's 1 MHz, so it will not work in higher-frequency applications. Pinout is standard quad op-amp, so it drops into the same DIP-14 socket.
Standard quad op-amp pinout for a 14-pin DIP: pin 1 (output A), pin 2 (inverting input A), pin 3 (non-inverting input A), pin 4 (V+), pin 5 (non-inverting input B), pin 6 (inverting input B), pin 7 (output B), pin 8 (output C), pin 9 (inverting input C), pin 10 (non-inverting input C), pin 11 (V- or GND), pin 12 (non-inverting input D), pin 13 (inverting input D), pin 14 (output D).
