Fairchild 74VHC393MTC — Dual 4-Bit Binary Counter, 2.0 V to 5.5 V, 170 MHz, TSSOP14, tube of 94 pieces. Two independent 4-bit ripple counters in a single package, enabling 8-bit counting or frequency division with one IC. Triggers on the negative-going clock edge with asynchronous active-HIGH clear per section. Ultra-low quiescent current of 4 µA max, 0 V to 7 V input protection for 5 V-to-3 V interfacing, and pin/function compatibility with 74HC393. Lead-free per JEDEC J-STD-020B.
