74CBTLV3244
8-bit bus switch with 4-bit output enables
Rev. 4 — 8 April 2019
Product data sheet
1. General description
The 74CBTLV3244 is a dual 4-pole, single-throw bus switch. The device features two output
enable inputs (nOE) that each control four switch channels. The switches are disabled when the
associated nOE input is HIGH. Schmitt trigger action at control 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.

Typical values are measured at Tamb = 25 °C and nominal VCC.
Measured by the voltage drop between the A and B terminals at the indicated current through the switch. ON-state resistance is
determined by the lower of the voltages of the two (A or B) terminals.

All typical values are measured at Tamb = 25 °C and at nominal VCC.
The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the load capacitance,
when driven by an ideal voltage source (zero output impedance).
tpd is the same as tPLH and tPHL.
