Part Details:

74VHCT541A OCTAL BUS BUFFER WITH 3 STATE OUTPUTS (NON INVERTED) s HIGH SPEED: t PD = 4.1 ns (TYP.) at VCC = 5V s LOW POWER DISSIPATION:ICC = 4 µA (MAX.) at TA=25°C s COMPATIBLE WITH TTL OUTPUTS:VIH = 2V (MIN.), VIL = 0.8V (MAX) s POWER DOWN PROTECTION ON INPUTS & OUTPUTS SOP TSSOP s SYMMETRICAL OUTPUT IMPEDANCE:|IOH| = IOL = 8 mA (MIN) Table 1: Order Codes s BALANCED PROPAGATION DELAYS:tPLH tPHL PACKAGE T & R s OPERATING VOLTAGE RANGE: SOP 74VHCT541AMTR VCC(OPR) = 4.5V to 5.5V TSSOP 74VHCT541ATTR s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 541 In order to enhance PC board layout, the s IMPROVED LATCH-UP IMMUNITY 74VHCT541 offers a pinout having inputs and s LOW NOISE: VOLP = 0.9V (MAX.) outputs on opposite sides of the package.Power down protection is provided on all inputs DESCRIPTION and outputs and 0 to 7V can be accepted on The 74VHCT541A is an advanced high-speed inputs with no regard to the supply voltage. This CMOS OCTAL BUS BUFFER (3-STATE) device can be used to interface 5V to 3V since all fabricated with sub-micron silicon gate and inputs are equipped with TTL threshold. 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 and G2 are high, all them 2KV ESD immunity and transient excess eight outputs are in the high impedance state. voltage.
