GeneralGeneral 2. 2. GeneralGeneral The TC7LX1104WBG is an advanced high-speed dual-supply 4-bit bus transceiver fabricated with silicon-gate CMOS technology. The TC7LX1104WBG is designed for use as an interface between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3- V voltage systems. The voltage translator automatically senses the direction of data transmission, eliminating the need for a direction control input. When the Output Enable (OE) input is low, the device is disabled, effectively isolating the buses. All inputs and outputs of the TC7LX1104WBG can tolerate overvoltage conditions up to 3.6 V. 3. 3. 3. 3. FeaturesFeaturesFeaturesFeatures (1) Voltage translation between arbitrary voltage levels from 1.2 V to 3.6 V. (2) High-speed operation: t = 5.7 ns (max) (V = 1.8 0.15 V, V = 3.3 0.3 V) pd CCA CCB (3) Latch-up performance: 300 mA (4) ESD performance: Machine model 200 V, Human body model 2000 V (5) Ultra-small package: WCSP12 (6) The A-bus and B-bus are allowed to float. (when OE = Low) (7) 3.6-V tolerant function and power-down protection provided on all inputs and outputs. (8) All output ports are disabled when either V is switched off (V =0V) CC CCA/B 2011-06-20 1 Rev.6.0TC7LX1104WBG 4. 4. 4. 4.
