Product details
Overview
TLC254CN from Texas Instruments is a LinCMOS™ quad operational amplifier optimized for low-power, single-supply operation across 1.4 V to 16 V. It delivers 10 mV max input offset voltage (25°C), 4 mA typical supply current (VDD = 5 V), 25 nV/√Hz input noise at 1 kHz, and rail-to-rail common-mode input range extending to the negative rail - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC254CN datasheet, TLC254CN pinout, TLC254CN application, or TLC254CN equivalent, this device is selected for ultra-low-input-bias-current analog front-ends requiring stable DC accuracy, wide supply flexibility, and ESD-hardened operation up to 2000 V per MIL-STD-883C Method 3015.1.
Technical Context
The TLC254CN uses Texas Instruments' silicon-gate LinCMOS™ process to achieve pA-level input bias and offset currents, high input impedance (>10¹² Ω), and stable offset voltage over temperature. Its internal electrostatic discharge (ESD) protection network prevents catastrophic failure under 2000 V HBM stress.
Designed for unity-gain stability, it supports true single-supply operation with common-mode input voltage including the negative rail (GND), enabling ground-referenced transducer interfacing without level-shifting circuitry. The device operates across 0°C to 70°C and is characterized for plastic DIP (N) packaging.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464CDR | Lower 1.2 µV/°C offset drift, 600 µA supply current, rail-to-rail output only (not input), 2.7–6 V supply range. | Requires ≥2.7 V supply; unsuitable for 1.4–2.5 V battery operation but offers better AC performance above 10 kHz. | Select TLV2464CDR when higher bandwidth (2.2 MHz GBW) and lower drift are prioritized over ultra-low-voltage operation. |
| LM324N | Bipolar input (20 nA bias current), 3 mV max offset, 1.2 mA supply current, 3–32 V supply, no ESD rating specified. | Lacks pA-level input impedance and ESD hardening; suitable for cost-sensitive, non-battery, non-precision applications. | Select LM324N only for legacy designs where input impedance >10⁹ Ω and ESD immunity are not required. |
Compared with TLV2464CDR and LM324N, the TLC254CN uniquely supports 1.4 V operation with pA input bias and 2000 V HBM ESD protection - making it irreplaceable in ultra-low-voltage, high-impedance, and field-deployed analog signal chains.

FAQ
What is the maximum input offset voltage specification for TLC254CN at 25°C?
The TLC254CN has a maximum input offset voltage of 10 mV at 25°C, as specified in the SLOS003G datasheet under "Electrical Characteristics at VDD = 5 V." This value applies to the 'C' grade (commercial temperature range) and defines the worst-case DC error introduced by the amplifier in precision gain or buffer configurations using the TLC254CN.
Does TLC254CN support true single-supply operation with input voltage down to ground?
Yes, the TLC254CN supports true single-supply operation with its common-mode input voltage range extending to the negative rail (GND). Per the datasheet, at VDD = 5 V, the common-mode input range is –0.2 V to 4 V - confirming that signals referenced to ground can be directly applied to either input of the TLC254CN without external level-shifting circuitry.
What is the typical supply current for TLC254CN at 5 V and 25°C?
The typical supply current for TLC254CN is 4 mA at VDD = 5 V and TA = 25°C, measured across all four amplifiers with no load. This value is confirmed in the "Electrical Characteristics" table on page 6 of the SLOS003G datasheet under IDD for TLC254C at 25°C, and reflects the device's balance of speed and ultra-low-power capability within the LinCMOS™ family.
Is TLC254CN pin-compatible with other devices in the TLC25x4 family?
Yes, the TLC254CN shares identical pinout and package (14-pin PDIP-N) with all variants in the TLC25x4 family, including TLC254ACN, TLC254BCN, TLC25L4CN, and TLC25M4CN. Differences lie solely in input offset voltage grade (2/5/10 mV), bias current profile (low/medium/high), and resulting slew rate/noise - not pin assignment or footprint.
What ESD protection level does TLC254CN provide, and how is it tested?
The TLC254CN incorporates internal electrostatic discharge (ESD) protection circuits rated to 2000 V human-body model (HBM), tested per MIL-STD-883C, Method 3015.1. This rating is explicitly stated in the "Description" section of the SLOS003G datasheet and confirms robustness against handling-induced static discharge during assembly and field service - though parametric degradation may occur with repeated exposure above rating.
