74CBTLV3384
10-bit bus switch with 5-bit output enables
Rev. 2 — 16 December 2011
Product data sheet
1. General description
The 74CBTLV3384 is a dual 5-pole, single-throw bus switch. The device features two
output enable inputs (nOE) that each control five 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 I
OFF
. The I
OFF
circuitry disables the output,
preventing the damaging backflow current through the device when it is powered down.
2. Features and benefits
Supply voltage range from 2.3 V to 3.6 V
High noise immunity
Complies with JEDEC standard:
JESD8-5 (2.3 V to 2.7 V)
JESD8-B/JESD36 (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
CDM AEC-Q100-011 revision B exceeds 1000 V
5
switch connection between two ports

(1) This is not a supply pin. The substrate is attached to this pad using conductive die attach material. There is no electrical or
mechanical requirement to solder this pad. However, if it is soldered, the solder land should remain floating or be connected to
GND.
