NXP Semiconductors 74LVC827A
The 74LVC827A is a high performance, low-power, low-voltage Si-gate CMOS device and superior to most advanced CMOS compatible TTL families. 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.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
Inputs can be driven from either 3.3V or 5.0V devices. In 3-state operation, outputs can handle 5V. A HIGH on OEn causes the outputs to assume a high impedance OFF-state.
