• Manufacturer Part Number: DSP56371D
• Description: high density CMOS device
• Manufacturer: Motorola Inc

Note:
6.0
The timing waveforms shown in the AC electrical characteristics section are tested with a V
0.8V and a V
input signal, are measured in production with respect to the 50% point of the respective input signal’s
transition. DSP56371 output levels are measured with the production test machine V
levels set at 1.0V and 1.8V, respectively.
