The SN74HC688PWR is an 8-bit identity comparator designed to compare two 8-bit binary or BCD words. Manufactured by Texas Instruments, this component operates within a wide voltage range of 2 V to 6 V. It features high-current outputs capable of driving up to 10 LSTTL loads and a low input current of 1 μA maximum. The device has an Active Low output and performs an A=B comparison.
This comparator is housed in a 20-TSSOP surface-mount package, measuring 4.40mm in width. The operating temperature range is -40°C to 85°C. Its typical propagation delay is 14 ns at 6V with a 50pF load, though other sources indicate up to 36 ns. The quiescent current is a low 80 μA maximum.
Key specifications include an 8-bit comparison capability, an Active Low output function (A=B), and a wide operating voltage range. The device is suitable for applications requiring digital word comparison where low power consumption and standard logic levels are important.
