– 1000-V Charged-Device Model (C101) DESCRIPTION
This 2-bit noninverting translator uses two separate
configurable power-supply rails. The A port is
designed to track VCCA. VCCA accepts any supply
voltage from 0.9 V to 3.6 V. The B port is designed to
track VCCB. VCCB accepts any supply voltage from
0.9 V to 3.6 V. This allows for low-voltage
bidirectional translation between 1-V, 1.2-V, 1.5-V, …
