General description
The 74LVCH32244A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3 V or 5 V devices. In 3-state operation, outputs can handle 5 V. These features allow the use of these devices in a mixed 3.3 V and 5 V environment.
The 74LVCH32244A is a 32-bit non-inverting buffer/line driver with 3-state outputs. The 3-state outputs are controlled by eight output enable inputs (1OE to 8OE). A HIGH on pin nOE causes the outputs to assume a high-impedance OFF-state.
To ensure the high-impedance state during power up or power down, pin nOE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The 74LVCH32244A bushold data inputs eliminates the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level.
Features
- 5 V tolerant inputs/outputs for interfacing with 5 V logic
- Wide supply voltage range of 1.2 V to 3.6 V
- CMOS low power consumption
- MULTIBYTE flow-trough standard pin-out architecture
- Low inductance multiple power and ground pins for minimum noise and ground bounce
- Direct interface with TTL levels
- Inputs accept voltages up to 5.5 V
- All data inputs have bushold
- Complies with JEDEC standard JESD8-B/JESD36
- ESD protection:
- Specified from -40 Cel to +85 Cel
- Packaged in plastic fine-pitch ball grid array package.
-
HBM EIA/JESD22-A114-B exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V.
