Octal D-Type Transparent Latches With 3-State Outputs The SN74ALS573CNSR is a part manufactured by Texas Instruments (TEXAS). Below are its specifications, descriptions, and features:
### **Specifications:**
- **Manufacturer:** Texas Instruments (TEXAS)
- **Part Number:** SN74ALS573CNSR
- **Type:** Octal Transparent D-Type Latch with 3-State Outputs
- **Technology:** Advanced Low-Power Schottky (ALS)
- **Package:** 20-pin SOP (Small Outline Package)
- **Operating Voltage (VCC):** 4.5V to 5.5V
- **Operating Temperature Range:** 0°C to 70°C
- **Output Type:** 3-State (High-Impedance, High, Low)
- **Input/Output Compatibility:** TTL
- **Latch Enable (LE) Input:** Active High
- **Output Enable (OE) Input:** Active Low
### **Descriptions:**
- The SN74ALS573CNSR is an octal transparent latch designed for bus-organized systems.
- It features 3-state outputs for direct connection to a bus line.
- Data is latched when the Latch Enable (LE) input is high, and outputs follow inputs.
- When LE is low, data is held in the latch.
- The Output Enable (OE) input controls the 3-state outputs, allowing multiple devices to share a common bus.
### **Features:**
- **Octal D-Type Latch:** 8-bit transparent latch with 3-state outputs.
- **Bus-Compatible Outputs:** Supports bus sharing with high-impedance state.
- **Low Power Consumption:** ALS technology ensures efficient power usage.
- **High-Speed Operation:** Optimized for fast data transfer.
- **Wide Operating Voltage Range:** 4.5V to 5.5V.
- **TTL-Compatible Inputs and Outputs:** Ensures compatibility with standard TTL logic.
- **Industrial Standard Pinout:** 20-pin SOP package for easy integration.
