Integrated Circuit, Dual 4-Stage Binary Counter, DIP-14

General Features

• Dual 4-stage independent binary counter
• DIP-14 package (14 pins)
• Full static operation
• Buffered inputs
• Common power supply for both counters

Electrical Specifications

• Supply voltage: 4.5V to 5.5V
• High-level input voltage (VIH): Minimum 2.0V
• Low-level input voltage (VIL): Maximum 0.8V
• High-level output voltage (VOH): Minimum 3.7V (with TTL load)
• Low-level output voltage (VOL): Maximum 0.4V (with TTL load)

Speed Specifications

• Maximum clock frequency: 27MHz (typical at 5V)
• Minimum clock pulse width: 19ns (at 5V)
• Reset recovery time: 5ns
• Minimum reset pulse width: 16ns
• Propagation delay: 32ns (nCP to nQ0 at 5V)

Functional Description

The device contains two independent 4-stage binary counters with outputs for each stage. Each counter uses master-slave flip-flops triggered on the negative edge of the clock. The MR (Master Reset) input sets all counters to the zero state when in the high level. All inputs and outputs are buffered to improve performance.

The device is designed for binary counting applications in digital systems, with the capability to count up to 15 (4 bits) for each counter. Static operation allows the clock to be stopped without affecting the stored state.

Typical Applications

• Binary counting in digital systems
• Frequency dividers
• Timers and stopwatches
• Logic sequence control
• Interface with microcontrollers
• Education and project development

Pin Assignment

• 1CP: Counter 1 Clock
• 1MR: Counter 1 Reset
• 1Q0-Q3: Counter 1 Outputs
• 2CP: Counter 2 Clock
• 2MR: Counter 2 Reset
• 2Q0-Q3: Counter 2 Outputs
• VCC: Positive supply (5V)
• GND: Ground

Technical Advantages

• Low power consumption
