Product details
Overview
77052012C from Maxim Integrated is a monolithic CMOS analog multiplexer with 8-channel single-pole configuration, ±15V dual supply operation, 400Ω typical ON-resistance, 50dB channel-to-channel isolation at 200kHz, and qualified to MIL-STD-883 Class B for aerospace and defense signal routing applications.
For engineers reviewing the 77052012C datasheet, 77052012C pinout, 77052012C application, or 77052012C equivalent, key selection criteria include guaranteed -55°C to +125°C operating range, 20-pin ceramic LCC package with thermal resistance ΘJA = 110°C/W, break-before-make timing of 5ns, and compliance with MIL-PRF-38535 screening requirements.
Technical Context
The 77052012C implements an 8:1 analog multiplexer using CMOS transmission-gate architecture with TTL-compatible digital control inputs (A0–A2, EN), enabling precise analog signal selection in high-reliability systems. It supports rail-to-rail analog input voltage range from (V−) −2V to (V+) +2V and features internal clamping diodes for overvoltage protection.
Designed for military-grade environments, it undergoes burn-in at +125°C for 1000 hours and full Group A/C/D testing per MIL-STD-883, including steady-state life test and capacitance validation (CA = 10pF, COS = 45pF). Its 20-pin CQCC1-N20 ceramic LCC package provides hermetic sealing and low ΘJC = 20°C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | 8:1 single-ended analog multiplexer - selects one of eight analog inputs to common output under digital address control. |
| Supply Voltage Range | ±15V (V+ to V− = 44V max) - supports wide dynamic range analog signal switching without level-shifting circuitry. |
| ON-Resistance | 400Ω typical (rDS(ON1)) at ±10V signal swing - ensures minimal insertion loss and gain error in precision measurement paths. |
| Channel Isolation | 50dB at 200kHz - suppresses crosstalk between active and inactive channels in multi-sensor data acquisition. |
| Break-Before-Make Delay | 5ns - prevents momentary shorting between channels during address transitions, critical for fault-tolerant systems. |
| Operating Temperature | -55°C to +125°C ambient - validated for deployment in avionics, missile guidance, and downhole instrumentation. |
| Package Type | CQCC1-N20 (20-pin ceramic LCC) - hermetically sealed, leadless surface-mount package with ΘJA = 110°C/W for thermal reliability. |
Pinout & Package
77052012C is housed in a 20-pin ceramic leadless chip carrier (CQCC1-N20, package code L20), featuring a 0.050″ pitch, 0.300″ × 0.300″ body, and glass-sealed construction for moisture resistance and long-term stability in harsh environments.

|---|---|---|
| 1 | IN1 | Analog input channel 1 - routed to output when A2A1A0 = 000 and EN = H. |
| 2 | IN2 | Analog input channel 2 - selected when A2A1A0 = 001 and EN = H. |
| 3 | IN3 | Analog input channel 3 - enabled by address 010 and active enable. |

| 7 | IN7 | Analog input channel 7 - selected on address 110. |
| 8 | IN8 | Analog input channel 8 - selected on address 111. |
| 9 | OUT | Common analog output terminal - delivers selected channel signal with ≤400Ω rDS(ON). |
| 10 | V+ | Positive analog supply - must be ≥|V−| and ≤+22V referenced to GND. |
| 11 | GND | Digital/analog reference ground - shared return for supplies and logic interface. |
| 12 | A2 | MSB address input - TTL-compatible, controls channel selection bit 2. |
| 13 | A1 | Address input bit 1 - determines middle bit of 3-bit channel address. |
| 14 | A0 | LSB address input - completes 3-bit binary address for 8-channel decode. |
| 15 | EN | Active-high enable - disables all switches (high-Z state) when low. |
| 16 | V− | Negative analog supply - must be ≤−22V referenced to GND; sets lower rail for analog signal range. |
| 17–20 | No Connect | Unused terminals - internally unconnected and must remain floating or grounded per layout guidelines. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG508ATQ/883B | Same 8:1 topology, but uses different process; rDS(ON) = 450Ω typ, ΘJA = 125°C/W in 20-lead CERDIP. | Higher thermal resistance and wider rDS(ON) tolerance - less suitable for low-error precision gain paths. | Select when legacy ADI supply chain alignment is required and thermal margin exceeds 15°C. |
| HI-508AJ/883B | Pin-compatible 20-pin LCC variant; rDS(ON) = 350Ω typ, but only specified over −55°C to +105°C. | Limited high-temperature performance - not qualified for sustained +125°C operation per MIL-PRF-38535. | Choose for cost-sensitive programs where full Class B screening is not mandated. |
Compared with ADG508ATQ/883B and HI-508AJ/883B, the 77052012C offers superior thermal performance (ΘJA = 110°C/W), tighter rDS(ON) control (400Ω typ), and full +125°C qualification - making it optimal for thermally constrained, high-reliability platforms where signal fidelity and lifetime assurance are non-negotiable.

FAQ
What is the maximum analog input voltage range supported by the 77052012C?
The 77052012C supports an analog input voltage range of (V−) −2V to (V+) +2V. With ±15V supplies, this translates to −17V to +17V absolute input capability. Internal clamping diodes limit forward current to rated levels, and exceeding (V−) −3V or (V+) +2V risks permanent damage per Absolute Maximum Ratings.
Does the 77052012C require external pull-up or pull-down resistors on its digital control pins?
No, the 77052012C does not require external biasing on A0, A1, A2, or EN. Its TTL-compatible inputs have defined VIH = 2.4V min and VIL = 0.8V max, and input leakage remains within ±0.8µA across temperature. External resistors may be used only for noise immunity in high-EMI environments, not for basic functionality.
How is the 77052012C screened for high-reliability applications?
The 77052012C undergoes full MIL-STD-883 screening per Method 5004 (burn-in at +125°C) and Method 5005 (Group A/B/C/D testing), including 1000-hour steady-state life test and electrical validation across −55°C to +125°C. It complies with MIL-PRF-38535 Class B quality assurance requirements for space-qualified components.
Can the 77052012C operate with asymmetric supply voltages such as +12V and −5V?
Yes, the 77052012C allows asymmetric supplies as long as V+ to V− ≤ 44V and each supply stays within its GND-referenced limits (+22V for V+, −22V for V−). For example, +12V/−5V yields a 17V differential - well within rating - and maintains full analog input range from −7V to +14V.
What is the thermal resistance from junction to ambient (ΘJA) for the 77052012C's 20-pin LCC package?
The 77052012C in its CQCC1-N20 ceramic LCC package has a specified ΘJA of 110°C/W. This value assumes standard JEDEC test board conditions and enables accurate junction temperature estimation: TJ = TA + (PDISS × 110°C/W), where PDISS is calculated from supply currents and switching losses.
