The MM74C192 and MM74C193 are synchronous 4-bit up/down decade counter and synchronous 4-bit up/down binary counter.
This document describes the MM74C192 and MM74C193, which are high noise margin monolithic complementary MOS (CMOS) integrated circuits. The MM74C192 is a BCD counter, while the MM74C193 is a binary counter. Both devices feature preset inputs, asynchronous clear, and carry/borrow outputs for cascading.

The MM74C192 is a BCD counter, while the MM74C193 is a binary counter.
Yes, they have carry and borrow outputs so that they can be cascaded using no external circuitry.
