74VHCT257A - Quad 2-channel multiplexer

General Description

t(s The 74VHCT257A is an advanced high-speed c CMOS quad 2 channel multiplexer (3-state) du fabricated with sub-micron silicon gate and ro double-layer metal wiring C2MOS technology.

(OE).

Key Features

  • High speed: tPD = 4.8 ns (typ. ) at VCC = 5 V.
  • Low power dissipation ICC = 4 μA (max. ) at TA = 25 °C ).
  • Compatible with TTL outputs t(s VIH = 2 V (min. ), VIL = 0.8 V (max. ) c.
  • Power-down protection on inputs and outputs du.
  • Symmetrical output impedance ro |IOH| = IOL = 8 mA (min. ) P.
  • Balanced propagation delays: tPLH ≅ tPHL te.
  • Operating voltage range: VCC(opr) = 4.5 to 5.5 V le.
  • Pin and function compatible with 74 series 257 so.
  • Improved latch-up.
