10-bit buffer/line driver with 5-volt tolerant inputs/outputs (3-State)
74LVC827A
FEATURES
* 5-volt tolerant inputs/outputs, for interfacing with 5-volt logic * Supply voltage range of 2.7V to 3.6V * Complies with JEDEC standard no. 8-1A * CMOS low power consumption * Direct interface with TTL levels * High impedance when VCC = 0V
DESCRIPTION
The 74LVC827A 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 3.3V or 5.0V devices. In 3-state operation, outputs can handle 5V. This feature allows the use of these devices as translators in a mixed 3.3V/5V environment. The 74LVC827A is a10-bit buffer/line driver with 3-State outputs The 3-State outputs are controlled by the output enable inputs OE1 and OE2. A HIGH on OEn causes the outputs to assume a high impedance OFF-state.

NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in W) PD = CPD x VCC2 x fi ) (CL x VCC2 x fo) where: fi = input frequency in MHz; CL = output load capacity in pF; fo = output frequency in MHz; VCC = supply voltage in V; (CL x VCC2 x fo) = sum of the outputs. 2. The condition is VI = GND to VCC

NOTES: 1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
