Choose TL064CN when low quiescent current is more important than wide small-signal bandwidth, fast large-signal response or low input-voltage noise. Choose TL074CN when the analog path needs higher gain bandwidth, faster slew rate, lower noise and tighter offset limits. Both are active, quad operational amplifiers in 14-pin PDIP packages, but the electrical tradeoff must be requalified before substitution.

Key differences
TL064CN reduces the amplifier supply-current budget
TI lists 0.2 mA typical quiescent current per channel for TL064 and 1.4 mA per channel for TL074. Across four channels, this is a meaningful power and thermal tradeoff for battery-operated or always-on signal paths.
TL074CN provides more signal bandwidth and faster settling
TL074 has a 3 MHz typical gain-bandwidth product and 13 V/µs typical slew rate, compared with 1 MHz and 3.5 V/µs for TL064. The higher-speed part is the stronger candidate when closed-loop bandwidth, full-power response or settling time controls the design.
TL074CN has the lower published noise and offset limits
TI lists 18 nV/√Hz typical input-voltage noise at 1 kHz and 6 mV maximum input offset at 25°C for TL074, versus 42 nV/√Hz and 15 mV for TL064. Verify the complete error budget at the intended gain, source impedance, bandwidth and temperature.
Can these parts be interchanged?
TL064CN and TL074CN share a 14-pin PDIP package, four amplifier channels and the same published 0°C to +70°C orderable temperature range, but a drop-in replacement must not be assumed from package similarity alone. Recheck the current TI pin functions, supply range, common-mode and output swing, stability, load drive, quiescent current, noise, offset, bandwidth, slew-rate requirement and worst-case closed-loop behavior. Prototype the change across supply, temperature, source impedance and output load before releasing the BOM.

TL064CN vs TL074CN FAQ
What is the main difference between TL064CN and TL074CN?
TL064CN prioritizes low quiescent current, while TL074CN provides higher gain bandwidth and slew rate with lower published input-voltage noise and offset limits. Select from the complete signal, power and error budget.
Which device is better for a low-power analog design?
TL064CN is usually the closer starting point when amplifier supply current dominates because TI lists 0.2 mA typical quiescent current per channel, compared with 1.4 mA per channel for TL074.
Which device is better for faster or lower-noise signal paths?
TL074CN is the stronger candidate when the design needs its 3 MHz typical gain bandwidth, 13 V/µs typical slew rate, 18 nV/√Hz typical noise density at 1 kHz or tighter offset limit.
Are TL064CN and TL074CN pin-compatible?
Both exact orderable codes use a 14-pin PDIP package, but package equality is not a complete compatibility determination. Confirm the current pinout, electrical limits, stability, load, supply and closed-loop behavior before substitution.
Can TL074CN replace TL064CN without changing the power budget?
No. TI lists a higher typical quiescent current per channel for TL074. Recalculate total amplifier current, battery life, regulator loading and thermal margin before replacing TL064CN with TL074CN.
