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 use as an interface between a 3.3V bus and a 2.5V or 1.8V bus in a mixed 3.3V/1.8V, 3.3V/2.5V, 1.8V/1.4V and 2.5V/1.8V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation.

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

|IOHA| = IOLA = 6mA Min at

VCCA = 2.3V; 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 (1.2V data retent)

VCCB(Opr) = 1.4V to 3.6V (1.2V data retent)

■ 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
