Description

The 74HC541 is an advanced high-speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with silicon gate C2MOS technology. The M74HC541 is a non inverting buffer. The 3-STATE control gate operates as a two input AND such that if either G1and G2are high, all eight output are in the high impedance state.

Features

1. High Speed : tPD = 9ns (TYP.) at VCC = 6V
2. LOW POWER DISSIPATION : ICC = 4µA(MAX.) at TA=25°C
3. HIGH NOISE IMMUNITY : VNIH = VNIL = 28 % VCC (MIN.)
4. SYMMETRICAL OUTPUT IMPEDANCE : |IOH| = IOL = 6mA (MIN)
5. BALANCED PROPAGATION DELAYS : tPLH ≅ tPHL
6. WIDE OPERATING VOLTAGE RANGE : VCC (OPR) = 2V to 6V
7. PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 541
