Description and Introduction

OCTAL D-TYPE LATCH WITH 3 STATE OUTPUT (NON INVERTING) The M74HC373 is an octal transparent latch with 3-state outputs manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Number of Bits:** 8 (Octal)  
- **Latch Type:** Transparent (data passes through when enable is high)  
- **Output Type:** 3-state (high, low, high-impedance)  
- **Supply Voltage Range:** 2V to 6V  
- **High Noise Immunity:** CMOS technology  
- **Low Power Consumption:** Typical ICC = 4µA (max)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** DIP-20, SO-20, TSSOP-20  

### **Descriptions:**  
The M74HC373 is an 8-bit transparent latch featuring 3-state outputs. It is commonly used in bus-oriented applications where multiple devices share a common data bus. When the latch enable (LE) input is high, the data inputs (D0-D7) pass through to the outputs (Q0-Q7). When LE is low, the outputs hold the last data present before the transition. The output enable (OE) pin controls the 3-state outputs, allowing them to be disabled (high-impedance state) when necessary.  

### **Features:**  
- **High-Speed Operation:** Compatible with TTL levels  
- **3-State Outputs:** Allows bus sharing  
- **Wide Operating Voltage:** 2V to 6V  
- **Balanced Propagation Delays:** Ensures stable performance  
- **Low Input Current:** 1µA (max)  
- **ESD Protection:** Exceeds 2000V (HBM)
