Actually what pandaemonium is talking about is the RTL series of IC's.
I have an old Motorola data book that lists 2 versions the MC723F and G one is in a metal can and the other is flatpack. Both require 3.6V +/- 10% for Vcc. I did find the MC723P in an old data book. 14 pin dip package. Pins as follows
Pin function
2 T
3 R
4 Common
5 Q
9 RD
10 Q not
11 Vcc
12 S
I even found one of the plastic package's in my stock of parts.
Hope this helps
