DESCRIPTION

The 74LVX4245 is a dual supply low voltage CMOS OCTAL BUS TRANSCEIVER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. Designed for use as an interface between a 5V bus and a 3.3V bus in a mixed 5V/3.3V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation.

■ HIGH SPEED: tPD = 8.5 ns (MAX.) at VCCA=5.0V VCCB = 3.3V

■ LOW POWER DISSIPATION: ICCA = ICCB =5μA(MAX.) at TA=25°C

■ LOW NOISE: VOLP =0.3V (TYP.) at VCCA=5.5V VCCB=3.3V

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 24mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH ? tPHL

■ OPERATING VOLTAGE RANGE: VCCA(OPR) = 4.5V to 5.5V (1.2V Data Retention) VCCB(OPR) = 2.7V to 3.6V (1.2V Data Retention) PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 4245

■ IMPROVED LATCH-UP IMMUNITY

74LVX4245屬于集成電路（IC） > 緩沖器，驅(qū)動器，接收器，收發(fā)器。意法半導(dǎo)體（ST）集團制造生產(chǎn)的74LVX4245緩沖器，驅(qū)動器，接收器，收發(fā)器邏輯緩沖器、驅(qū)動器、接收器和收發(fā)器允許隔離對某個電路的邏輯信號的訪問，以用于另一電路。緩沖器將其輸入信號（不變或反相）傳遞到其輸出，并可能用于清除弱信號或驅(qū)動負載。在布爾邏輯仿真器中，緩沖器主要用于增加傳播延遲。邏輯接收器和收發(fā)器允許在數(shù)據(jù)總線之間進行隔離通信。
