The LVCH162244A is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.
The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer.
This device provides true outputs and symmetrical active-low output-enable (OE) inputs.
All pins of this 16-bit buffer/driver can be driven from either 3.
3V or 5V devices.
This feature allows the use of this device as a translator in a mixed 3.
3V/5V supply system.
The LVCH162244A has series resistors in the device output structure which will significantly reduce line noise when used with light loads.
This driver has been developed to drive ±12mA at the designated threshold levels.
The LVCH162244A has “bus-hold” which retains the inputs’ last state whenever the input goes to a high impedance.
This prevents floating inputs and eliminates the need for pull-up/down resistors.
DRIVE FEATURES: • Balanced Output Drivers: ±12mA • Full internal series termination APPLICATIONS: • 5V and 3.
3V mixed voltage systems • Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM 1OE 1 3OE 25 1A1 47 2 1Y1 3A1 36 13 3Y1 1A2 46 3 1Y2 3A2 35 14 3Y2 1A3 44 5 1Y3 3A3 33 16 3Y3 1A4 43 6 1Y4 3A4 32 17 3Y4 2OE 48 4OE 24 2A1...
