The M74LS160P is a synchronous decade counter manufactured by Mitsubishi. This integrated circuit is a high-speed, synchronous, presettable decade counter with direct clear and count enable inputs. It's typically used in frequency dividers, event counters, and digital timers.

Applications

• Frequency Dividers
• Event Counters
• Digital Timers
• Address Generation

Features

• Function: Synchronous Decade Counter
• Family: 74LS
• Counting Range: 0 to 9 (BCD)
• Supply Voltage: 4.75V to 5.25V
• Clock Input: Positive-edge triggered
• Clear Input: Direct (asynchronous)
• Count Enable Inputs: Two enable inputs (CEP, CET)
• Package: DIP-16 (Plastic Dual In-Line Package)

Benefits

• Synchronous Operation: All flip-flops are clocked simultaneously, ensuring clean counting.
• Presettable: Can be preset to any desired count value.
• Direct Clear: Asynchronous clear input allows for immediate reset.
• Count Enable: Two enable inputs provide flexible control over counting.
• Standard TTL Logic: Compatible with other 74LS series devices.

Additional Details

The M74LS160P operates synchronously, meaning all flip-flops change state simultaneously on the rising edge of the clock pulse. The count enable inputs (CEP and CET) must both be high for the counter to increment. The direct clear input, when low, immediately resets the counter to zero. The preset inputs are loaded into the counter when the load input is low. This device is a fundamental building block for digital timing and counting applications.
