SN74LVCH245A - Octal Bus Transceiver With 3-State Outputs

The SN54LVCH245A octal bus transceiver is designed for 2.7-V to 3.6-VV_CC operation, and the SN74LVCH245A octal bus transceiver is designed for1.65-V to 3.6-V V_CC operation. Inputs can be driven from either 3.3-V or 5-Vdevices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V systemenvironment.

• Operate From 1.65 V to 3.6 V
• Inputs Accept Voltages to 5.5 V
• Max t_pd of 6.3 ns at 3.3 V
• Typical V_OLP (Output Ground Bounce)
  <0.8 V at V_CC = 3.3 V, T_A = 25°C
• Typical V_OHV (Output V_OH Undershoot)
  >2 V at V_CC = 3.3 V, T_A = 25°C
• Support Mixed-Mode Signal Operation on All Ports (5-V Input/Output Voltage With
  3.3-V V_CC)
• I_off Supports Live Insertion, Partial-Power-Down Mode, and Back-Drive Protection
• Bus Hold on Data Inputs Eliminates the Need for External Pullup or Pulldown Resistors
• Latch-Up Performance Exceeds 250 mA Per JESD 17
• ESD Protection Exceeds JESD 22
  • 2000-V Human-Body Model (A114-A)
  • 200-V Machine Model (A115-A)
• On Products Compliant to MIL-PRF-38535,
  All Parameters Are Tested Unless Otherwise Noted. On All Other Products, Production Processing Does Not Necessarily Include Testing of All Parameters.
