OCTAL D-TYPE LATCH WITH 3-STATE OUTPUT The TC74ACT373FW is a high-speed octal D-type latch manufactured by Toshiba. Below are its key specifications, descriptions, and features:
### **Specifications:**
- **Logic Type:** Octal Transparent Latch (3-State)
- **Technology:** Advanced CMOS (ACT)
- **Supply Voltage Range:** 4.5V to 5.5V
- **High-Speed Operation:**
- Propagation Delay: **5.5ns (max) @ 5V, 25°C, CL = 50pF**
- **Output Drive Capability:**
- **24mA (min) at VCC = 5V**
- **Low Power Consumption:**
- **ICC (Static): 4μA (max) @ 5V**
- **Operating Temperature Range:** **-40°C to +85°C**
- **Package Type:** **TSSOP-20 (FW package)**
### **Descriptions:**
- The TC74ACT373FW is an octal transparent latch with 3-state outputs, designed for bus-oriented applications.
- It features a latch enable (LE) input and an output enable (OE) input for controlling data flow.
- When LE is high, the outputs (Q) follow the data inputs (D). When LE goes low, the data is latched.
- The 3-state outputs allow multiple devices to be connected to a common bus.
### **Features:**
- **High-Speed CMOS Technology:** Ensures fast switching performance.
- **3-State Outputs:** Allows bus sharing in multi-device systems.
- **Wide Operating Voltage Range:** 4.5V to 5.5V.
- **Balanced Propagation Delays:** Optimized for high-speed operation.
- **Low Power Consumption:** Suitable for battery-operated devices.
- **ESD Protection:** Provides robustness against electrostatic discharge.
- **TSSOP Package:** Compact footprint for space-constrained designs.
