Folks,
When interfacing TTL to CMOS, please remember that the
automotive environment is rather harsh and demanding.
Any such interface must function with sufficient noise
immunity accross the full expected operational
temperature range.
With that in mind, please use the appropriate
published manufacturers recommendations for the
devices. In order to meet the specifications that
their large customers demand, these have been
researched, proven, and are guaranteed*.

* actually, the percentage that will fail to work is
guaranteed, but it's usually a vanishingly small number.
