The SN74HC688DWR from Texas Instruments is an 8-bit identity comparator designed to compare two 8-bit binary or BCD words. It features a wide operating voltage range from 2V to 6V, making it suitable for various applications. The device offers high-current outputs capable of driving up to 10 LSTTL loads and has a low power consumption of 80 μA maximum ICC.
This comparator has a typical propagation delay of 14 ns and provides ±4 mA output drive at 5 V. It also features a low input current of 1 μA maximum. An output-enable (OE) input is available to force the output to a high level.
The SN74HC688DWR is supplied in a 20-SOIC package with surface mount capabilities. It operates within a temperature range of -40°C to 85°C. This component is ideal for digital logic applications requiring precise word comparison.
Key specifications include an 8-bit comparison capability, a supply voltage range of 2V to 6V, and a maximum propagation delay of 36ns at 6V and 50pF. The device's output function is A=B and it is active low.
