The 54F162DM is a synchronous 4-bit decade counter manufactured by Rochester Electronics. This device is part of the 54F series of high-speed, advanced TTL (Transistor-Transistor Logic) logic circuits. Rochester Electronics remanufactures this component, ensuring continued availability for applications where the original part is no longer available from the original manufacturer.

Applications

• Frequency dividers in test equipment.
• Digital clocks and timers.
• Instrumentation and measurement devices.
• Industrial control systems.
• General-purpose counting applications in digital systems.

Features

• Synchronous counting operation.
• High-speed operation due to advanced TTL technology.
• Internal look-ahead carry for fast counting.
• Clear input for resetting the counter.
• Count enable inputs for controlling the counting operation.
• BCD (Binary Coded Decimal) output.

Benefits

• Reliable counting performance due to synchronous design.
• High-speed operation enables use in demanding applications.
• Easy to interface with other TTL logic circuits.
• Reduced component count due to integrated functionality.
• Guaranteed availability through Rochester Electronics' remanufacturing program.

Additional Details

The 54F162DM operates over the full military temperature range. It comes in a ceramic dual in-line package (CERDIP). The synchronous operation means that all flip-flops are clocked simultaneously, eliminating timing skew problems. The internal look-ahead carry circuitry allows for high-speed cascading of multiple counters. The device's clear input asynchronously resets the counter to zero, independent of the clock signal. The count enable inputs provide control over the counting operation, allowing for conditional counting or holding the current count value. This device offers a stable and predictable solution for decade counting needs.
