The SN74LVCH16245ADGGR is a 16-bit non-inverting Bus Transceiver with 3-state outputs and designed for 1.65 to 3.6V VCC operation. This device is designed for asynchronous communication between data buses. This device can be used as two 8-bit transceivers or one 16-bit transceiver. Active bus-hold circuitry holds unused or un-driven data inputs at a valid logic state. The logic levels of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the A-port outputs or place both output ports into the high-impedance mode. The device transmits data from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated. Active bus-hold circuitry holds unused or un-driven data inputs at a valid logic state. Use of pull-up/pull-down resistors with the bus-hold circuitry is not recommended. The bus-hold circuitry is part of the input circuit and is not disabled by OE or DIR.
● Supports mixed-mode signal operation on all ports
● IOFF Supports live insertion, partial-power-down mode and back-drive protection
● Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
● Latch-up performance exceeds 250mA per JESD 17
● 4ns at 3.3V Propagation delay (tpd)
● <0.8V at VCC = 3.3V, TA = 25°C VOLP (output ground bounce)
● >2V at VCC = 3.3V, TA = 25°C VOHV (output VOH undershoot)
● Green product and no Sb/Br
