There is a PI-451 and a PI-451A.
The PI-451 is described as a "MOS/CCD Driver", the PI-451A as a "Programmable Pulse Driver."
The PI-451 is described as a "MOS/CCD Driver."
The PI-451A is described as a "Programmable Pulse Driver."


For driving FPA and CCD clocks in a multi-channel system, the modern equivalents from Pulse Instruments are:
A TTL-level input pulse controls an output with programmable high and low voltages and transition times.
