Rochester Electronics 54F191/QFA Environmental and export classification status description
- Part Number: 54F191/QFA - Type: 4-bit Binary Synchronous Up/Down Counter - Family: TTL (Transistor-Transistor Logic) - Package: Ceramic Flat Pack 2. Functions: - Counts up or down based on the clock input signal. - Parallel load capability for setting the initial count. - Supports synchronous counting, parallel loading, and cascading for extended counting applications. 3. Applications: - Industrial control systems - Electronic counters and timers - Frequency dividers - Digital clocks - Automotive systems 4. Alternative Components: - 74LS191: Similar 4-bit up/down counter with a different logic family (Low-Power Schottky). - CD4516: 4-bit synchronous up/down counter in the CMOS logic family. - SN54/74LS192: 4-bit binary counter with parallel load in the TTL family. 5. Embedded Modules: - The 54F191/QFA can be integrated into larger digital systems for applications requiring counting and control functions. - It can be combined with other logic gates, flip-flops, and interface components to create custom digital circuits. Related Q&A: Q1: What is the maximum clock frequency supported by the 54F191/QFA IC? A1: The maximum clock frequency for the 54F191/QFA typically ranges from 25MHz to 30MHz, depending on the operating conditions. Q2: Can the 54F191/QFA be cascaded to increase the counting range? A2: Yes, multiple 54F191/QFA ICs can be cascaded together to increase the counting range and achieve larger counter widths. Q3: How does the parallel load feature work in the 54F191/QFA? A3: The parallel load feature allows the user to preset the initial count value by simultaneously loading the desired binary data into the counter using the parallel inputs. Q4: What are the power supply voltage requirements for the 54F191/QFA IC? A4: The 54F191/QFA typically operates with a power supply voltage in the range of 4.5V to 5.5V. Q5: Does the 54F191/QFA have built-in ripple blanking capability? A5: Yes, the 54F191/QFA includes a ripple blanking input that allows the user to inhibit the ripple-carry output during counting operations for noise reduction.
