FAST CMOS 8-BIT IDENTITY COMPARATOR The IDT74FCT521CTQ is a high-speed, low-power octal transparent latch manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:
### **Specifications:**
- **Logic Type:** Octal Transparent Latch
- **Number of Bits:** 8
- **Supply Voltage (VCC):** 4.5V to 5.5V
- **High-Level Input Voltage (VIH):** 2.0V (min)
- **Low-Level Input Voltage (VIL):** 0.8V (max)
- **High-Level Output Voltage (VOH):** 2.4V (min) @ IOH = -3mA
- **Low-Level Output Voltage (VOL):** 0.5V (max) @ IOL = 24mA
- **Propagation Delay (tPD):** 5.5ns (max)
- **Operating Temperature Range:** -40°C to +85°C
- **Package Type:** TSSOP-20
### **Descriptions:**
- The IDT74FCT521CTQ is an 8-bit transparent latch with 3-state outputs.
- It features a latch enable (LE) input and an output enable (OE) input for control.
- When LE is high, data passes through the latch transparently. When LE is low, data is latched.
- The OE pin controls the 3-state outputs, allowing them to be disabled (high impedance).
### **Features:**
- **High-Speed Operation:** Optimized for performance with low propagation delay.
- **Low Power Consumption:** Designed for reduced power usage.
- **3-State Outputs:** Allows for bus-oriented applications.
- **TTL-Compatible Inputs:** Ensures compatibility with TTL logic levels.
- **ESD Protection:** Provides protection against electrostatic discharge.
- **Industrial Temperature Range:** Suitable for harsh environments.
