The Tektronix M123A (P/N 155-0119-00) is a 5-digit BCD counter and multiplexer monolithic integrated circuit in a 40-pin CERDIP, desigend by Dave Allstot.
It provides a multiplexed BCD output with decoded digit lines from its five internal counter stages plus four latched 4-bit BCD inputs (for the most significant digits i.e. higher frequency divider stages). Maximum clock frequency is 5 MHz.
