72241L10PF

The 72241L10PF is an IC chip that belongs to the logic FIFOs memory category. It is a First-In First-Out (FIFO) memory device with a total of 10 address lines. The chip is defined by the following parameters:• Input Register Size : 16 words X 10 bits• Output Register Size : 16 words X 10 bits• RAM Size : 10 words X 10 bits• Voltages : 5V Vcc, Vss-0.5V & Vee (Adjustable)The primary function of this chip is to store data in FIFO order. It features WR (write) and RD (read) access, along with full and empty flag. The device has separate address and data interconnects, as well as a user-programmable FIFO depth. The integrated-circuit (IC) also has a TTL-compatible input pin that enables independent chip select and chip enable logic. Chip select CS and Chip enable CE can be used to control multiple 72241L10PF devices in parallel.This device is used in various applications such as in instrumentation, logic-mapping, memory-cascading, multiplexing and in electronic switch control. It can also be used for data queuing and buffering in peripherals like modems and disk drives.The basic working principle of the 72241L10PF is that when enabled, the chip reads the data from the highest address and writes it in the FIFO register, or it reads the data from the register and writes it in the lowest address.The FIFO is a "circular" type buffer with the oldest data written in the first slot. Data is first written in the first slot of the FIFO register, when it is full, then the new data is written in the next slot and so on. When the FIFO register is ‘empty’, the oldest data is continuously read from the first slot.The 72241L10PF has two flags – full and empty flags – used to indicate when the chip is full or empty. The status of the full and empty flags is evaluated at the rising edge of the clock signal.The 91T139 integrated circuit is usually used in conjunction with the 72241L10PF for creating a 2k-bit FIFO memory. The 91T139 serves as the controller for the FIFO device. When data is written to the 72241L10PF, the 91T139 increments the address counter and sends the write command to the 72241L10PF. When data is read from the 72241L10PF, the 91T139 decrements the address counter and sends the read command to the 72241L10PF. Overall, the 72241L10PF is a very functional device and can be used in numerous scenarios due to its wide array of features. The chip is reliable and has a low power consumption rate. It is widely available and has numerous configurations available for different applications.
