Description and Introduction

Synchronous 4-Bit Up/Down Counters (Dual Clock With Clear) The SN54192J is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments (TM).  

### **Specifications:**  
- **Type:** Synchronous 4-bit Up/Down Counter  
- **Logic Family:** TTL (Transistor-Transistor Logic)  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Counting Modes:** Up, Down, and Parallel Load  
- **Clock Inputs:** Separate Up and Down clock inputs  
- **Outputs:** 4-bit binary output (Q0, Q1, Q2, Q3)  
- **Carry & Borrow Outputs:** Provides ripple carry and borrow signals for cascading  
- **Package:** 16-pin CDIP (Ceramic Dual In-line Package)  

### **Descriptions and Features:**  
- **Synchronous Operation:** All flip-flops are clocked simultaneously, reducing output delay.  
- **Parallel Load Capability:** Allows presetting the counter via parallel data inputs.  
- **Independent Clocking:** Separate up (CP↑) and down (CP↓) clock inputs for flexible counting direction control.  
- **Clear Function:** Asynchronous master reset (MR) for immediate counter clearing.  
- **Cascadable:** Carry (TCU) and Borrow (TCD) outputs enable multi-stage counting.  
- **High-Speed Operation:** Suitable for high-frequency counting applications.  

This part is designed for military and industrial applications requiring reliable performance under extreme conditions.

Description and Introduction

Synchronous 4-Bit Up/Down Counters (Dual Clock With Clear) The SN54192J is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Synchronous 4-Bit Up/Down Counter  
- **Count Sequence:** Up or Down (Programmable)  
- **Operating Voltage:** 4.5V to 5.5V  
- **Clock Frequency:** Typically up to 25 MHz  
- **Output Type:** TTL (Transistor-Transistor Logic)  
- **Number of Bits:** 4  
- **Reset Function:** Asynchronous Master Reset (MR)  
- **Load Function:** Parallel Load Capability  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Package Type:** Ceramic DIP (Dual In-line Package)  

### **Descriptions:**  
- The SN54192J is a high-speed synchronous counter with individual preset inputs for each flip-flop.  
- It features separate up and down clock inputs for bidirectional counting.  
- The counter can be cleared asynchronously using the Master Reset (MR) pin.  
- It includes carry and borrow outputs for cascading multiple counters.  

### **Features:**  
- **Synchronous Operation:** All flip-flops change state simultaneously.  
- **Programmable Count Direction:** Selectable up or down counting.  
- **Parallel Load Capability:** Allows presetting the counter to a desired value.  
- **Asynchronous Master Reset:** Clears all outputs regardless of clock state.  
- **Carry/Borrow Outputs:** Facilitates cascading multiple counters.  
- **High-Speed TTL Compatibility:** Suitable for high-performance digital systems.  

This information is based on the manufacturer's datasheet for the SN54192J.
