The 74AHCT07A is a hex buffer with open-drain outputs. The outputs are open-drain and can be connected to other open-drain outputs to implement active-LOW wired-OR or active-HIGH wired-AND functions.
Designed to operate over a VCC range from 4.5 V to 5.5 V, the inputs are TTL compatible, which allows the device to be used to translate from 3.3 V to 5 V.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
This device is fully specified for partial Power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
Features and benefits
Direct interface with TTL levels
Supply voltage range from 4.5 V to 5.5 V
Typical tPZL of 3.4 ns at 5 V
Typical VOL(p) < 0.8 V at VCC = 5 V, Tamb = 25 °C
Supports mixed-mode voltage operation on all ports
IOFF circuitry provides partial Power-down mode operation
Latch-up performance exceeds 250 mA per JESD 78 Class II
ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 3000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 2000 V
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
