The device is designed for low voltage (2.5V and 3.3V) V CC applications. The T/R input deter-mines the direction of data flow through the device. The OE input disables both the A and B ports by placing them in a high impedance state. The 26Ω series resistor in the B Port output helps reduce output overshoot and undershoot.The LCXH2245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain-ing CMOS low power dissipation.The LCXH2245 data inputs include active bushold circuitry,eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level.Featuress 5V tolerant control inputss 2.3V–3.6V V CC specifications provideds Bushold on inputs eliminates the need for external pull-up/pull-down resistors s 7.0 ns t PD max (V CC = 3.3V), 10 µA I CC max s Power down high impedance outputs s ±12 mA output drive B Port (V CC = 3.0V)s Implements patented noise/EMI reduction circuitry s Latch-up performance exceeds 500 mA s Equivalent 26Ω series resistor on B Port outputs s ESD performance:Human body model > 2000V Machine model > 200VOrdering Code:Devices also available in T ape and Reel.

Inputs can be driven from either 3.3 or 5 V devices. This feature allows the use of these devices as translators in a mixed 3.3 and 5 V environment. The 74LVC38A provides the 2-input NAND function. The outputs of the 74LVC38A devices are open drain and can be connected to other open-drain outputs to implement active-LOW wired-OR or active-HIGH wired-AND functions.
