ST1G3234B - 1-bit dual supply bus buffer level translator

General Description

The ST1G3234B 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.

Key Features

  • High speed: tPD = 4.0 ns (max. ) at TA = 85 °C VCCB = 1.65 V; VCCA = 3.0 V Low power dissipation: ICCA = ICCB = 5 μA (max. ) at TA = 85 °C Symmetrical output impedance: |IOHA| = IOLA = 10 mA min at VCCA = 2.75 V; VCCB = 1.4 to 3.6 V |IOHA| = IOLA = 6 mA min. at VCCA = 2.3 V; VCCB = 1.4 to 3.6 V Balanced propagation delays: tPLH ≅ tPHL Power-down protection on inputs and outputs 26 Ω series resistor on A-side outputs Operating voltage range:.
  • VCCA (opr. ) = 1.4 to 3.6 V.
