DESCRIPTION

· The ST1G3234 is a dual supply low voltage CMOS 1-Bit bus buffer level translator.

· Fabricated with sub-micron silicon gate and five-layer metal wiring C2MOS technology.

· Designed for interfacing between 3.3V bus and 2.5V or 1.8V bus in mixed supply systems.

· Ensures high-speed operation while maintaining low power dissipation.

· Intended for one-way asynchronous communication between data buses.

· Features input and output power down protections for effective bus isolation.

· Input tolerant buffers allow translation of VCCB compatible signals to VCCA.

· All inputs are equipped with protection circuits against static discharge.

FEATURES

· High speed: tPD = 4.4ns (Max.) at TA = 85°C, VCCB = 1.65V; VCCA = 3.0V.

· Low power dissipation: ICCA = ICCB = 5µA(Max.) at TA = 85°C.

· Symmetrical output impedance: |IOHA| = IOLA = 10mA Min at VCCA = 2.75V; VCCB = 1.4V to 3.6V.

· Balanced propagation delays: tPLH ≅ tPHL.

· Power down protection on inputs and outputs.

· 26Ω series resistor on A-side outputs.

· Operating voltage range: VCCA(Opr) = 1.4V to 3.6V; VCCB(Opr) = 1.4V to 3.6V.

· Max data rates: 380Mbps (1.8V to 3.3V translation), 260Mbps (<1.8V to 3.3V translation), 260Mbps (translate to 2.5V), 210Mbps (translate to 1.5V).

· Latch-up performance exceeds 500mA (JESD 17).

· ESD performance: HBM > 2000V (MIL STD 883 method 3015); MM > 200V.

· ROHS compliant for Flip-Chip package.
