FEATURES
74ALVT16652
DESCRIPTION
• 16–bit bus interface
• 5V I/O Compatible
• 3-State buffers
• Output capability: +64mA/-32mA
• TTL input and output switching levels
• Input and output interface capability to systems at 5V supply
• Bus-hold data inputs eliminate the need for external pull-up
The 74ALVT16652 is a high-performance BiCMOS product
designed for VCC operation at 2.5V or 3.3V with I/O compatibility up
to 5V. The device can be used as two 8-bit transceivers or one
16-bit transceiver.
Complimentary output-enable (OEAB and OEBA) inputs are
provided to control the transceiver functions. Select-control (SAB
and SBA) inputs are provided to select whether real-time or stored
data is transferred. A Low-input level selects real-time data, and a
High input level selects stored data. The circuitry used for select
control eliminates the typical decoding glitch that occurs in a
multiplexer during the transition between stored and real-time data.
resistors to hold unused inputs
• Live insertion/extraction permitted
• Power-up reset
• Power-up 3-State
• No bus current loading when output is tied to 5V bus
• Latch-up protection exceeds 500mA per JEDEC JC40.2 Std 17
• ESD protection exceeds 2000V per MIL STD 883 Method 3015
Data on the A or B bus, or both, can be stored in the internal
flip-flops by Low-to-High transitions at the appropriate clock (CPAB
or CPBA) inputs regardless of the levels on the select-control or
output-enable inputs. When SAB and SBA are in real-time transfer
mode, it is possible to store data without using the internal D-type
flip-flops by simultaneously enabling OEAB and OEBA. In this
configuration, each output reinforces its input. Thus, when all other
data sources to the two sets of bus lines are at high impedance,
each set of bus lines remains at its last level configuration.

Low-to-High clock transition
The data output function may be enabled or disabled by various signals at the nOEBA and nOEAB inputs. Data input functions are
always enabled, i.e., data at the bus pins will be stored on every Low-to-High transition of the clock.
If both Select controls (nSAB and nSBA) are Low, then clocks can occur simultaneously. If either Select control is High, the clocks must
be staggered in order to load both registers.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.

NOTES:
1. All typical values are at VCC = 3.3V and Tamb = 25°C.
2. This is the increase in supply current for each input at the specified voltage level other than VCC or GND
3. This parameter is valid for any VCC between 0V and 1.2V with a transition time of up to 10msec. From VCC = 1.2V to VCC = 3.3V ± 0.3V a
transition time of 100µsec is permitted. This parameter is valid for Tamb = 25°C only.
4. Unused pins at VCC or GND.
5. ICCZ is measured with outputs pulled up to VCC or pulled down to ground.
6. For valid test results, data must not be loaded into the flip-flops (or latches) after applying power.
7. This is the bus hold overdrive current required to force the input to the opposite logic state.

NOTES:
1. All typical values are at VCC = 2.5V and Tamb = 25°C.
2. This is the increase in supply current for each input at the specified voltage level other than VCC or GND
3. This parameter is valid for any VCC between 0V and 1.2V with a transition time of up to 10msec. From VCC = 1.2V to VCC = 2.5V ± 0.2V a
transition time of 100µsec is permitted. This parameter is valid for Tamb = 25°C only.
4. Unused pins at VCC or GND.
5. ICCZ is measured with outputs pulled up to VCC or pulled down to ground.
6. Not guaranteed.
7. For valid test results, data must not be loaded into the flip-flops (or latches) after applying power.

Definitions
Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
Application information — Applications that are described herein for any of these products are for illustrative purposes only. Philips
Semiconductors make no representation or warranty that such applications will be suitable for the specified use without further testing or
modification.
