Description and Introduction

CMOS Digital Integrated Circuit Silicon Monolithic BCD-to-7 Segment Latch/Decoder/Driver The TC74HC4511AP is a BCD-to-7-segment latch/decoder/driver manufactured by Toshiba. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Logic Family:** HC (High-Speed CMOS)  
- **Supply Voltage Range (VCC):** 2V to 6V  
- **Input Voltage (VI):** 0V to VCC  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Current (IO):** ±25mA  
- **Propagation Delay Time (tpd):** 13ns (typical at VCC = 5V)  
- **Package Type:** DIP-16  

### **Descriptions:**
- The TC74HC4511AP is a CMOS integrated circuit that converts a 4-bit binary-coded decimal (BCD) input into a 7-segment display output.  
- It includes an internal latch to store the BCD input, a decoder to convert the BCD data, and a driver to control the 7-segment display.  
- It is designed for common-cathode 7-segment LED displays.  

### **Features:**
- **BCD-to-7-Segment Decoder:** Converts 4-bit BCD input into 7-segment outputs.  
- **Latch Function:** Holds the input data when the latch enable (LE) is high.  
- **High Output Current:** Capable of driving LEDs directly (up to 25mA per segment).  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **Blanking Input (BI):** Forces all segment outputs to off when activated.  
- **Lamp Test (LT):** Turns on all segments for testing purposes.  

The TC74HC4511AP is commonly used in digital display applications such as counters, clocks, and instrumentation panels.
