74系列逻辑芯片/74AHCT244D
DESCRIPTION
The 74AHC/AHCT244 is a high-speed Si-gate CMOS device. The 74AHC/AHCT244 is an octal non-inverting buffer/line driver with 3-state outputs. The 3-state outputs are controlled by the outputs enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high-impedance OFF state.
FEATURES
• ESD protection:
HBM EIA/JESD22-A114-A exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V
CDM EIA/JESD22-C101 exceeds 1000 V
• Balanced propagation delays
• All inputs have a Schmitt-trigger action
• Inputs accepts voltages higher than VCC
• For AHC only: operates with CMOS input levels
• For AHCT only: operates with TTL input levels
• Specified from −40 to +85 and +125°C.
