DESCRIPTION
The 54HC541 is an advanced high-speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with silicon gate C2MOS technology. The M54HC541 is a non inverting buffer.
The 3-STATE control gate operates as a two input
AND such that if either G1 and G2 are high, all eight output are in the high impedance state. In order to enhance PC board layout the M54HC541 offer a pinout having inputs and outputs on opposite sides of the package.
All inputs are equipped with protection circuits against static discharge and transient excess voltage.
■ HIGH SPEED: tPD = 9ns (TYP.) at VCC = 6V
■ LOW POWER DISSIPATION: ICC = 4µA(MAX.) at TA=25°C
■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.)
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 6mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH 54 SERIES 541
