POST OFFICE BOX 1443
HOUSTON, TEXAS 77251–1443
external divide-by-two clock option
An external frequency source can be used by injecting the frequency directly into X2 /CLKIN with X1 left
unconnected, CLKMD1 set high, and CLKMD2 set high. The external frequency is divided by two to generate
the internal machine cycle. The external frequency injected must conform to specifications listed in the timing
requirements table.

This device utilizes a fully static design and therefore can operate with tc(CI) approaching ∞. The device is characterized at frequencies
approaching 0 Hz, but is tested at a minimum of 6.7 MHz to meet device test time requirements.
