General description
The 74LVC821A is a high performance, low power, low voltage Si-gate CMOS device and superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3 V or 5 V devices. In 3-state operation, outputs can handle 5 V. This feature allows the use of these devices as translators in a mixed 3.3 V and 5 V environment.

Features
■ 5 V tolerant inputs and outputs; for interfacing with 5 V logic
■ Wide supply voltage range from 1.2 V to 3.6 V
■ Inputs accept voltages up to 5.5 V
■ CMOS low power consumption
■ Direct interface with TTL levels
■ Flow-through pin-out architecture
■ 10-bit positive edge-triggered register
■ Independent register and 3-state buffer operation
■ Complies with JEDEC standard JESD8-B
■ ESD protection:
   ◆ HBM EIA/JESD22-A114-B exceeds 2000 V
   ◆ MM EIA/JESD22-A115-A exceeds 200 V.
■ Specified from −40 °C to +85 °C and −40 °C to +125 °C.
