74LVCH244A OCTAL BUFFER/LINE DRIVER WITH BUS HOLD / 3 STATE OUTPUTS
■The 74LVCH244A provides two 4-bit line drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
■The device is designed for operation with a power supply range of 1.65V to 3.6V.
■The inputs are tolerant to 5.5V allowing this device to be used in a mixed voltage environment.The device is fully specified for partial power down applications using I-OFF.The I-OFF circuitry disables the output preventing damaging current backflow when the device is powered down.
■Bus hold circuitry holds unused or un-driven inputs at a high or low logic state.The use of external pull-up or pull down resistors is not recommended.
●Features:
■Supply Voltage Range from 1.65V to 3.6V
■Sinks or Sources 24mA at Vcc = 3V
■CMOS Low Power Consumption
■I-OFF Supports Partial-Power Down Operation
■Inputs or Outputs Accept up to 5.5V
■Inputs Can be Driven by 3.3V or 5V Allowing for Mixed Voltage Applications
■Schmitt Trigger Action at All Inputs
■Typical V-OLP (Quiet Output Ground Bounce) less than 0.8V with Vcc = 3.3V and T-A = +25°C
■Typical V-OHV (Quiet Output Dynamic VOH) greater than 2.0V with Vcc = 3.3V and T-A = +25°C
■ESD Protection Tested per JESD 22
■Exceeds 200-V Machine Model (A115)
■Exceeds 2000-V Human Body Model (A114)
■Exceeds 1000-V Charged Device Model (C101)
■Latch-Up Exceeds 250mA per JESD 78, Class I
■Totally Lead-Free & Fully RoHS compliant (Notes 1 & 2)
■Halogen and Antimony Free. Green” Device (Note 3)
