## AM26LS32AMDREP: Electronic Specifications and Overview The **AM26LS32AMDREP** is a high-performance Quadruple Differential Line Receiver designed for balanced digital data transmission. This specific part number belongs to the **Enhanced Product (EP)** family from Texas Instruments, meaning it is rated for military, aerospace, or high-reliability industrial applications. ### 1. Key Technical Specifications | Parameter | Specification | |:---|:---| | **Function** | Quadruple Differential Line Receiver | | **Technology** | Low-Power Schottky (LS) | | **Supply Voltage ($V_{CC}$)** | 4.75V to 5.25V (Standard 5V) | | **Input Sensitivity** | ±200 mV | | **Input Hysteresis** | 50 mV (Typical) | | **Output Type** | 3-State (High Impedance capability) | | **Operating Temperature** | -55°C to 125°C (Military Grade) | | **Package** | SOIC (D) or Other High-Reliability variants | --- ### 2. Functional Components The device consists of four independent receiver channels. Below are the core electronic characteristics of these parts: * **Differential Inputs:** It takes a pair of signals (A and B). It calculates the difference between them, which allows it to reject common-mode noise (EMI) effectively over long cables. * **Fail-Safe Design:** If the inputs are open-circuited, the receiver is designed to maintain a specific logic state (usually High) to prevent random data errors. * **3-State Outputs:** The outputs can be set to a high-impedance state using the Enable (G) and Enable Bar ($\bar{G}$) pins. This allows multiple devices to share a single data bus. * **LS Technology:** Uses Low-power Schottky circuitry, balancing high-speed switching with moderate power consumption. --- ### 3. Pinout Configuration (Standard 16-pin) | Pin Number | Name | Description | |:---:|:---|:---| | 1 | 1B | Inverting Input (Channel 1) | | 2 | 1A | Non-inverting Input (Channel 1) | | 3 | 1Y | Output (Channel 1) | | 4 | G | Active-High Enable | | 5 | 2Y | Output (Channel 2) | | 6 | 2A | Non-inverting Input (Channel 2) | | 7 | 2B | Inverting Input (Channel 2) | | 8 | GND | Ground | | 12 | $\bar{G}$ | Active-Low Enable | | 16 | $V_{CC}$ | Supply Voltage (5V) | --- ### 4. What the "AMDREP" Suffix Means The suffix provides critical information regarding the reliability and testing of the component: * **AM:** Original Military Prefix. * **26LS32:** Device family (Differential Receiver). * **M:** Military Temperature Range (-55°C to 125°C). * **D:** Package type (usually SOIC). * **REP:** **Enhanced Product**. This indicates controlled baseline, gold bond wires, and one assembly/test site, often used for defense or aerospace systems.
