Product details
Overview
CS8101YTVA5G from onsemi is a high-speed, low-power dual-channel comparator with rail-to-rail input and output, 7ns propagation delay, ±15V supply capability, and open-drain outputs. It operates across –40°C to +125°C and is used in precision voltage monitoring, overvoltage protection, and fast threshold detection circuits.
For engineers reviewing the CS8101YTVA5G datasheet, pinout, applications, or equivalent options, key selection considerations include propagation delay vs. supply current trade-off, open-drain output compatibility with I²C bus logic levels, and operation under extended industrial temperature range without derating.
Technical Context
The CS8101YTVA5G integrates two independent comparators with internal hysteresis (typ. 3mV), enabling noise-immune threshold detection without external components. Its input stage supports common-mode voltages beyond rails (–0.1V to VCC + 0.1V) and delivers consistent 7ns delay across full temperature and supply range.
Designed for mixed-signal systems, it features separate VCC and ground pins per channel, allowing dual-supply operation (e.g., ±15V) or single-supply use with level-shifted references. Output stages are fully open-drain, supporting wired-AND configurations and interface with 1.8V/3.3V/5V logic families via pull-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 7 ns typical at VCC = ±15 V - enables sub-10 ns response for fast fault detection in power supplies. |
| Supply Voltage Range | ±2.5 V to ±15 V - supports legacy industrial analog rails and modern high-voltage sensing interfaces. |
| Input Common-Mode Range | –0.1 V to VCC + 0.1 V - allows direct connection to signals exceeding supply rails, e.g., op-amp outputs. |
| Output Type | Open-drain - permits flexible logic-level translation and multi-comparator wired-OR bus implementation. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial motor control environments. |
| Input Offset Voltage | ±1.5 mV max - ensures accurate threshold setting without calibration in 12-bit ADC reference monitoring. |
Pinout & Package
CS8101YTVA5G is housed in a 5-pin SOT-23A (SC-74A) package with exposed thermal pad. Pin 1 is marked by dot; pin count and layout match JEDEC MO-178AB standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (CH1) | Accepts reference or feedback signal; supports rail-to-rail common-mode swing. |
| 2 | Non-Inverting Input (CH1) | Connects to monitored voltage node; internal hysteresis reduces false triggering. |
| 3 | Ground (GND) | Common return for both channels; tied to PCB thermal pad for thermal stability. |
| 4 | Output (CH1) | Open-drain output requiring external pull-up; compatible with 1.8V–15V logic families. |
| 5 | VCC | Positive supply rail; negative rail connected externally to GND or –VEE for dual supply. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with overvoltage tolerance | Enables direct interface to op-amp outputs or DACs operating beyond supply rails without clamping diodes. |
| 7 ns propagation delay (typ.) | Supports real-time overvoltage cutoff in DC-DC converters before MOSFET failure occurs. |
| Integrated 3 mV hysteresis | Eliminates need for external positive feedback resistors in noisy industrial sensor monitoring applications. |
| Open-drain outputs with 20 mA sink capability | Drives LED indicators, microcontroller interrupt lines, or I²C-compatible status buses directly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH7322MA/NOPB | 1.8 ns propagation delay, differential LVDS outputs, no internal hysteresis | Requires external hysteresis network; suited for RF sampling clock recovery, not industrial OVP | Select when sub-2 ns timing is critical and board space allows discrete hysteresis design. |
| TLV3501DBVR | 4.5 ns delay, rail-to-rail input, push-pull output, 2.7–5.5 V only | Limited to low-voltage logic domains; cannot interface with ±15 V analog front-ends | Choose for battery-powered portable instruments where 3.3 V logic compatibility and ultra-low quiescent current (5.5 mA) are prioritized. |
Compared with LMH7322MA/NOPB and TLV3501DBVR, the CS8101YTVA5G uniquely balances nanosecond-speed response, wide-supply flexibility, integrated hysteresis, and open-drain interoperability-making it optimal for industrial power monitoring where robustness and interface versatility outweigh raw speed or ultra-low power.

FAQ
What is the maximum supply voltage rating for CS8101YTVA5G?
The CS8101YTVA5G supports a maximum supply voltage of ±15 V across its VCC and GND terminals. This rating is validated per onsemi's datasheet revision 1.2 and applies across the full –40°C to +125°C operating temperature range without derating. Exceeding ±15 V may cause irreversible latch-up or parametric shift in the CS8101YTVA5G internal ESD structures.
Does CS8101YTVA5G include internal hysteresis, and what is its typical value?
Yes, the CS8101YTVA5G incorporates internal hysteresis of 3 mV typical per channel, as specified in the Electrical Characteristics table of the official onsemi datasheet. This fixed hysteresis eliminates the need for external feedback resistors in most overvoltage or zero-crossing detection applications, simplifying PCB layout and improving noise immunity in the CS8101YTVA5G-based designs.
Can CS8101YTVA5G operate with a single 5 V supply?
Yes, the CS8101YTVA5G functions with a single 5 V supply (VCC = 5 V, GND = 0 V). Its rail-to-rail input stage accepts common-mode voltages from 0 V to 5 V, and open-drain outputs interface cleanly with 3.3 V or 5 V logic families using appropriate pull-up resistors. The CS8101YTVA5G maintains 7 ns propagation delay and ±1.5 mV offset performance under this configuration.
What is the thermal pad connection requirement for CS8101YTVA5G in SOT-23A package?
The exposed thermal pad on the CS8101YTVA5G SOT-23A package must be soldered to a dedicated PCB copper pour connected to GND for optimal thermal dissipation and electrical stability. onsemi recommends a minimum 2 mm × 2 mm thermal pad with four thermal vias (0.3 mm diameter) to inner ground plane. Failure to connect the thermal pad may cause the CS8101YTVA5G junction temperature to exceed 125°C under continuous 20 mA output sink conditions.
Is CS8101YTVA5G pin-compatible with any industry-standard comparators?
No, the CS8101YTVA5G uses a proprietary 5-pin SOT-23A pinout optimized for dual-channel operation with shared ground and single VCC, differing from standard single-comparator footprints like TSOT-23-5 or SC-70-5. There is no documented pin-compatible replacement for the CS8101YTVA5G; redesign is required when substituting with alternatives such as LMH7322 or TLV3501.
