Important notice
Dear Customer,
On 7 February 2017 the former NXP Standard Product business became a new company with the
tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets

FEATURES
DESCRIPTION
• Complies with JEDEC standard
no. 8-1A
The 74ALVCH162601 is an 18-bit universal transceiver featuring non-inverting
3-state bus compatible outputs in both send and receive directions. Data flow
in each direction is controlled by output enable (OEAB and OEBA), and clock
(CPAB and CPBA) inputs. For A-to-B data flow, the device operates in the
transparent mode when LEAB is HIGH. When LEAB is LOW, the A data is
latched if CPAB is held at a HIGH or LOW logic level. If LEAB is LOW, the A-bus
data is stored in the latch/flip-flop on the LOW-to-HIGH transition of CPAB.
When OEAB is LOW, the outputs are active. When OEAB is HIGH, the outputs
are in the high-impedance state. The clocks can be controlled with the
clock-enable inputs (CEBA/CEAB).
• CMOS low power consumption
• Direct interface with TTL levels
• MULTIBYTE flow-through
standard pin-out architecture
• Low inductance multiple VCC and
ground pins for minimum noise and
ground bounce
• All data inputs have bus hold
circuitry
Data flow for B-to-A is similar to that of A-to-B but uses OEBA, LEBA and CPBA.
To ensure the high-impedance state during power-down, OEBA and OEAB
should be tied to VCC through a pull-up resistor, the minimum value of the
resistor is determined by the current-sinking/current-sourcing capability of the
driver.
• Integrated 30 Ω termination
resistors.
The 74ALVCH162601 is designed with 30 Ω series resistors in both HIGH or
LOW output stage.
Active bus hold circuitry is provided to hold unused or floating data inputs at
a valid logic level.

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
∑ (CL × VCC2 × fo) = sum of outputs;
CL = output load capacitance in pF;
VCC = supply voltage in Volts.
2. The condition is VI = GND to VCC.

Fig.6 The input An, Bn to output Bn, An propagation delay times.
Notes: VCC = 2.3 to 2.7 V
VM = 0.5VCC;
VX = VOL + 150 mV;
VY = VOH − 150 mV;
VI = VCC;
VOL and VOH are typical output voltage drop that occur with the output load.
Notes: VCC = 3.0 to 3.6 V and VCC = 2.7 V
VM = 1.5 V;
VX = VOL + 300 mV;
VY = VOH − 300 mV;
VI = 2.7 V;
VOL and VOH are typical output voltage drop that occur with the output load.
