MARKING DIAGRAMS

By Non−preferential Powerup Sequencing

Abstract

The NLSX3018 is a 8−bit configurable dual−supply bidirectional level translator without a direction control pin. The I/O VCC − and I/O VL−ports are designed to track two different power supply rails, VCC and VL respectively. The VCC supply rail is configurable from 1.3 V to 4.5 V while the VL supply rail is configurable from 0.9 V to (VCC − 0.4) V. This allows lower voltage logic signals on the VL side to be translated into higher voltage logic signals on the VCC side, and vice−versa. Both I/O ports are auto−sensing; thus, no direction pin is required. The Output Enable (EN) input, when Low, disables both I/O ports by putting them in 3−state. This significantly reduces the supply currents from both VCC and VL. The EN signal is designed to track VL
