The NLSX4014 is a 4-bit configurable dual-supply bidirectional level shifter that does not require a direction control pin. The IO VCC and IO VL ports are used to track two different power rails, VCC and VL, respectively. The VCC rail is configurable from 1.3 V to 4.5 V, while the VL rail is configurable from 0.9 V to (VCC - 0.4) V. This allows lower voltage logic signals on the VL side to be converted to higher voltage logic signals on the VCC side and vice versa. Both I/O ports are auto-sensing, eliminating the need for direction pins. The output enable (EN) input, when low, places both I/O ports in 3-state, thereby disabling them. This greatly reduces supply current from VCC and VL. The EN signal is used to track VL.
