74VHC541 OCTAL BUS BUFFER WITH 3 STATE OUTPUTS (NON INVERTED) s HIGH SPEED: t PD = 3.5 ns (TYP.) at VCC = 5V s LOW POWER DISSIPATION:ICC = 4 µA (MAX.) at TA=25°C s HIGH NOISE IMMUNITY:VNIH = VNIL = 28% VCC (MIN.) s POWER DOWN PROTECTION ON INPUTS SOP TSSOP s SYMMETRICAL OUTPUT IMPEDANCE:|IOH| = IOL = 8 mA (MIN) s BALANCED PROPAGATION DELAYS: Table 1: Order Codes tPLH tPHL s OPERATING VOLTAGE RANGE: PACKAGE T & R VCC(OPR) = 2V to 5.5V SOP 74VHC541MTR s PIN AND FUNCTION COMPATIBLE WITH TSSOP 74VHC541TTR 74 SERIES 541 s IMPROVED LATCH-UP IMMUNITY In order to enhance PC board layout, the s LOW NOISE: VOLP = 0.9V (MAX.) 74VHC541 offers a pinout having inputs andoutputs on opposite sides of the package. DESCRIPTION Power down protection is provided on all inputs The 74VHC541 is an advanced high-speed and 0 to 7V can be accepted on inputs with no CMOS OCTAL BUS BUFFER (3-STATE) regard to the supply voltage. This device can be fabricated with sub-micron silicon gate and used to interface 5V to 3V. double-layer metal wiring C2MOS technology. All inputs and outputs are equipped with The 3 STATE control gate operates as two input protection circuits against static discharge, giving AND such that if either G1 or G2 are high, all eight them 2KV ESD immunity and transient excess outputs are in the high impedance state. voltage.
