Part Details:

74LCX16646 Low February 1994 Revised August 2002 74LCX16646Low Voltage 16-Bit Transceiver/Register V with 5V Tolerant Inputs and Outputs oltage 16-Bi General Description Features The LCX16646 contains sixteen non-inverting bidirectional s 5V tolerant inputs and outputs registered bus transceivers with 3-STATE outputs, provid- s 2.3V­3.6V VCC specifications provided ing multiplexed transmission of data directly from the input s bus or from the internal storage registers. Each byte has 5.2 ns tPD max (VCC = 3.3V), 20 µA ICC max t T separate control inputs which can be shorted together for s Power down high impedance inputs and outputs full 16-bit operation.The DIR inputs determine the direction s Supports live insertion/withdrawal (Note 1) rans of data flow through the device. The CPAB and CPBA s ±24 mA Output Drive (V inputs load data into the registers on the LOW-to-HIGH CC = 3.0V) transition (see Functional Description). s Implements patented noise/EMI reduction circuitry ceiver The LCX16646 is designed for low voltage (2.5V or 3.3V) s Latch-up performance exceeds 500 mA VCC applications with capability of interfacing to a 5V signal s ESD performance: environment. Human Body Model > 2000V /Regi The LCX16646 is fabricated with an advanced CMOS tech- Machine Model > 200V nology to achieve high speed operation while maintaining Note 1: To ensure the high-impedance state during power up or down, OE CMOS low power dissipation. should be tied to VCC through a pull-up resistor: the minimum value or the s resistor is determined by the current-sourcing capability of the driver. te r w i Ordering Code: th 5V T Order Number Package Number Package Description 74LCX16646MEA
