74ALVT16601

18-bit universal bus transceiver; 3-state

Rev. 03 — 5 July 2005

Product data sheet

1. General description

The 74ALVT16601 is a high-performance Bipolar Complementary Metal Oxide

Semiconductor (BiCMOS) product designed for V_CCoperation at 2.5 V and 3.3 V with I/O

compatibility up to 5 V. This device 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), latch enable

(LEAB and LEBA), 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-bus

data is latched if CPAB is held at a HIGH or LOW 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 (CEAB and CEBA).

Data ﬂow for B-to-A is similar to that of A-to-B but uses OEBA, LEBA and CPBA.

Active bus hold circuitry is provided to hold unused or ﬂoating data inputs at a valid logic

level.

2. Features

[1] All typical values are at V_CC= 2.5 V and T_amb= 25 °C.

[2] For valid test results, data must not be loaded into the ﬂip-ﬂops (or latches) after applying power.

[3] Unused pins at V_CCor GND.

[4] Not guaranteed.

[5] This parameter is valid for any V_CCbetween 0 V and 1.2 V with a transition time of up to 10 ms. From V_CC= 1.2 V to V_CC= 2.5 V ± 0.2 V

a transition time of 100 µs is permitted. This parameter is valid for T_amb= 25 °C only.

[6] I_CCis measured with outputs pulled up to V_CCor pulled down to ground.

[7] This is the increase in supply current for each input at the speciﬁed voltage level other than V_CCor GND.

[8] All typical values are at V_CC= 3.3 V and T_amb= 25 °C.

[9] This is the bus hold overdrive current required to force the input to the opposite logic state.

[10] This parameter is valid for any V_CCbetween 0 V and 1.2 V with a transition time of up to 10 ms. From V_CC= 1.2 V to V_CC= 3.3 V ± 0.3 V

a transition time of 100 µs is permitted. This parameter is valid for T_amb= 25 °C only.

speciﬁed.

Limiting values deﬁnition — Limiting values given are in accordance with

the Absolute Maximum Rating System (IEC 60134). 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.
