The SN74AHCT573PW is Texas Instruments’ high-speed, low-power octal D-type flip-flop that provides eight bits of register storage for digital logic applications. Designed to operate from a single +5V to +15V power supply and specified for operation over the -40°C to +85°C temperature range, this device has a symmetrical output control making it easy to drive any signal from Vcc to Vee. And its wide output swings of 0.3 V to Vdd-1.3 V benefit from low power dissipation.

Application Field: Logic designers often use this device in the context of memory address decoding, where static address decoding is needed. It also proves useful in registers, arithmetic logic, shift registers, system clock distribution, counters and other applications. Typical application fields include Processors, solenoids, encoders, scanning circuits, and logic level converters.

Working Principle: The bit output from the device is simply the value stored at the input during the input setup time. The output may be enabled or disabled by use of the enable pin (EN). When enabled, EN is held low or at ground potential, while when disabled it is set to a high level (Vcc). The SN74AHCT573PW also features an active high reset line which clears all data stored in the device to a known state when triggered. The reset line is triggered typically in order to restarting the device, or whenever the device is powered off.

The device features an optional break before make (BBM) feature which guarantees that there are no “out of phase” connections when the device is changing bits. The BBM feature also prevents unintentional transfer of data from one bit to another. The device also provides an active-low output enable line which allows the outputs to be individually enabled or disabled. It also provides an individual data setup for each output bit, allowing the logic designer to adjust the device for different output levels.

In conclusion, the SN74AHCT573PW is an 8-bit static D-type latch that operates from a single +5V to +15V power supply and is capable of operating over the wide -40°C to +85°C temperature range. It features an active reset, a break before make option, and individual output enable and data setup signals, making it an ideal choice for encoding applications.
