Part Details:

74LVX257 LOW VOLTAGE CMOS QUAD 2 CHANNEL MULTIPLEXER (3-STATE) WITH 5V TOLERANT INPUTS s HIGH SPEED: tPD=5.8ns (TYP.) at VCC = 3.3V s 5V TOLERANT INPUTS s POWER-DOWN PROTECTION ON INPUTS s INPUT VOLTAGE LEVEL: VIL = 0.8V, VIH = 2V at VCC =3V s LOW POWER DISSIPATION: SOP TSSOP ICC = 4 µA (MAX.) at TA=25°C s LOW NOISE: Table 1: Order Codes VOLP = 0.3V (TYP.) at VCC =3.3V s SYMMETRICAL OUTPUT IMPEDANCE: PACKAGE T & R |IOH| = IOL = 4 mA (MIN) at VCC =3V SOP 74LVX257MTR s BALANCED PROPAGATION DELAYS: TSSOP 74LVX257TTR tPLH tPHL s OPERATING VOLTAGE RANGE:VCC(OPR) = 2V to 3.6V (1.2V Data Retention) multiplexer. When the ENABLE INPUT is held s PIN AND FUNCTION COMPATIBLE WITH "High", all outputs become in high impedance 74 SERIES 257 state. If SELECT INPUT is held "Low", "A" data is s IMPROVED LATCH-UP IMMUNITY selected, when SELECT INPUT is "High", "B" datais chosen. DESCRIPTION Power down protection is provided on all inputs The 74LVX257 is a low voltage CMOS QUAD 2 and 0 to 7V can be accepted on inputs with no CHANNEL MULTIPLEXER (3-STATE) fabricated regard to the supply voltage. with sub-micron silicon gate and double-layer This device can be used to interface 5V to 3V. It metal wiring C2MOS technology. It is ideal for low combines high speed performance with the true
