74VCX16245LBR 数据手册 ( 数据表 ) - STMicroelectronics

DESCRIPTION
The 74VCX16245 is a low voltage CMOS 16 BIT BUS TRANSCEIVER (3-STATE) fabricated with sub-micron silicon gate and five-layer metal wiring C2MOS technology. It is ideal for low power and very high speed 1.8 to 3.6V applications; it can be interfaced to 3.6V signal environment for both inputs and outputs. This IC is intended for two-way asynchronous communication between data buses; the direction of data transmission is determined by DIR input.

■ 3.6V TOLERANT INPUTS AND OUTPUTS
■ HIGH SPEED:
   tPD = 2.5 ns (MAX.) at VCC = 3.0 to 3.6V
   tPD = 3.2 ns (MAX.) at VCC = 2.3 to 2.7V
   tPD = 5.7 ns (MAX.) at VCC = 1.8V
■ POWER DOWN PROTECTION ON INPUTS AND OUTPUTS
■ SYMMETRICAL OUTPUT IMPEDANCE:
   |IOH| = IOL = 24mA (MIN) at VCC = 3.0V
   |IOH| = IOL = 18mA (MIN) at VCC = 2.3V
   |IOH| = IOL = 6mA (MIN) at VCC = 1.8V
■ OPERATING VOLTAGE RANGE: VCC(OPR) = 1.8V to 3.6V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 16240
■ LATCH-UP PERFORMANCE EXCEEDS 300mA (JESD 17)
■ ESD PERFORMANCE:
   HBM > 2000V (MIL STD 883 method 3015);
   MM > 200V
