Direct interface with TTL levels (2.7 to 3.6 V)
Power-down mode
Latch-up performance exceeds 250 mA
ESD protection:
HBM EIA/JESD22-A114-A exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V.
DESCRIPTION
The 74ALVC125 is a high-performance, low-power,
low-voltage, Si-gate CMOS device and superior to most
advanced CMOS compatible TTL families.
Schmitt-trigger action at all inputs makes the circuit
tolerant for slower input rise and fall times.
The 74ALVC125 consists of four non-inverting buffer/line
drivers with 3-state outputs. The 3-state outputs (nY) are
controlled by the output enable input (nOE). A HIGH on
pin nOE causes the outputs to assume a high-impedance
OFF-state.
