The 74AHC245; 74AHCT245 is an 8-bit transceiver with 3-state outputs. The device features an output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments. 2. Feat.
• Wide supply voltage range from 2.0 V to 5.5 V
• Balanced propagation delays
• All inputs have Schmitt-trigger action
• Overvoltage tolerant inputs to 5.5 V
• High noise immunity
• CMOS low power dissipation
• Input levels:
• For 74AHC245: CMOS level
• For 74AHCT245: TTL level
• ESD protection:
• HBM JESD22-A114F exceeds 2000 V
• MM JESD22-A115-A exceeds 200 V
• CDM JESD22-C101E exceeds 1000 V
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level A
• Multiple package options
• Specified from -40 °C to +85 °C and from -40 °C to +125 °C
