74VHC244 Datasheet | Nexperia

description The 74VHC244; 74VHCT244 are a high-speed Si-gate CMOS devices. The 74VHC244; 74VHCT244 have octal non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs are controlled by the output enable inputs (n OE). A HIGH on n OE causes the outputs to assume a high-impedance OFF-state. 2. Features and benefits - Balanced propagation delays - All inputs have a Schmitt-trigger action - Inputs accepts voltages higher than VCC - Input levels: - The 74VHC244 operates with CMOS input level - The 74VHCT244 operates with TTL input level - ESD protection: - HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V - CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V - Multiple package options - Specified from -40 °C to +85 °C and from -40 °C to +125 °C 3.
